Pre-draft Griffin was not perceived as a first-round draft pick prior to his junior season. By midseason, however, he had drawn the attention of NFL scouts and analysts, and some started projecting he would be an early first round selection. Towards the end of his junior season, Griffin had established himself as the No. 2 quarterback prospect for the
2012 NFL draft, behind the unanimous first pick projection
Andrew Luck. Griffin was widely projected to be the No. 2 pick of the draft, but the
St. Louis Rams—the team originally holding the pick—had already selected
Sam Bradford to be their long-term starting quarterback with the No. 1 overall pick in the
2010 NFL draft. Wanting to stick with Bradford, the Rams decided to deal the pick prior to the draft, with the
Cleveland Browns and
Washington Redskins perceived as the most interested bidders. After a brief bidding process, the Redskins acquired the pick by giving the Rams four high-value draft picks over three years: their first-round picks in 2012 (No.6 overall), 2013 (No.22 overall), and 2014 (No.2 overall), as well as their second-round pick (No.39 overall) in 2012.
Washington Redskins 2012 season As expected, the Redskins selected Griffin as the second overall pick, making him the second Baylor Bear to be drafted that high in four years (after
Jason Smith in 2009), but the first Baylor quarterback to be chosen second overall since
Adrian Burk in
1950. Griffin wore number 10 for the Redskins, with "Griffin III" on the back of his jersey. This made him the first player in the history of the "Big Four" professional sports leagues (
NFL,
MLB,
NHL, and
NBA) to have a
Roman numeral on the back of his jersey, as the NFL changed the rule in 2012 to allow players to include
generational titles in their names. Griffin previously had "Griffin III" on the back of his jersey while in college, which was necessary in order to distinguish him from
the other Robert Griffin on the Baylor team. On July 18, 2012, the Redskins signed him to a four-year, $21.1 million contract with a $13.8 million signing bonus. On September 9, 2012, Griffin became the NFL's first starting quarterback who was born in the 1990s. In his debut as a starting quarterback in the NFL, Griffin opened the Redskins' season by completing 19 of 26 passes for 320 yards and two touchdowns while adding 10 carries for 42 rushing yards in a 40–32 victory over the
New Orleans Saints. He was named
NFC Offensive Player of the Week for his performance – the first time in NFL history that a rookie quarterback has been given that honor for his debut game. Griffin's debut performance was further rewarded after he was named
NFL Rookie of the Week, and he was given that honor once again after the Redskins' win over the
Tampa Bay Buccaneers in Week 4. On October 4, he was named September's
NFL Offensive Rookie of the Month. The next week against the
Atlanta Falcons, he left the game late in the third quarter after suffering a mild concussion after receiving a blow to the head by
Sean Weatherspoon. He was cleared to play in the next game against the
Minnesota Vikings, where he had another impressive performance that included a 76-yard rushing touchdown. The Redskins ended their home-game losing streak and Griffin was named
NFL Rookie of the Week for a third time. On November 14 during the Redskins' bye week, the team voted Griffin an
offensive co-captain. Following the Redskins' 31–6 victory against the
Philadelphia Eagles, he was named
NFC Offensive Player of the Week for a second time. Griffin's performance – passing for 200 yards with 4 touchdowns, rushing for an additional 84 yards, and finishing with a perfect 158.3 passer rating – made him the first rookie in NFL history to pass for 200 yards, pass for 4 touchdowns and rush for more than 75 yards in a single game. Along with that achievement, his performance against the Eagles made him the youngest player in NFL history, at 22 years and 284 days old, to achieve a perfect passer rating in a game. This record stood until 2015 when
Tennessee Titans quarterback
Marcus Mariota threw for a perfect passer rating at 21 years and 318 days old in his debut. In the Week 14 game against the
Baltimore Ravens on December 9, the Redskins would suffer another injury scare when
defensive end Haloti Ngata hit Griffin directly at his right knee, twisting it in the process. On the final drive of the fourth quarter, Griffin was tackled after rushing for 13 yards and hopped on one leg for several plays before leaving the game. The next day it was confirmed that Griffin had sustained a Grade 1
LCL sprain. It was decided that Griffin would sit out the next game against the Browns to give him more time to heal and avoid the chance of further injuries. He returned the next game and led the Redskins to another victory over the Eagles in Week 16. The knee injury emerged as a controversy on January 6, the day the Redskins faced the
Seattle Seahawks in the NFC
wild card game, when
USA Today reported that – contrary to a previous statement made by head coach
Mike Shanahan – Dr.
James Andrews had not cleared Griffin to return for the post-injury plays in the December 9 game. Griffin then re-injured his knee in the wild card loss to the Seahawks. Griffin underwent surgery on January 9 and both his
LCL and
ACL were repaired. For the season, Griffin set records for highest passer rating by a rookie quarterback (102.4) and highest touchdown to interception ratio (4:1) (both since broken by
Dak Prescott). Aside from the week 15 game against the Cleveland Browns where he did not play, Griffin played a vital role in helping the Redskins finish the regular season on a 7-game winning streak after starting the season 3–6, leading the team to its first playoff appearance since the 2007 season. On December 26, Griffin was named to enter the
2013 Pro Bowl in recognition of his successful rookie season. Due to injuries on his ACL and LCL ligaments in his right knee, he was negated from the Pro Bowl roster and replaced by
Drew Brees. Griffin also won the
2012 NFL Offensive Rookie of the Year award. He was named to the
PFWA All-Rookie Team, becoming the second Redskins quarterback to receive this award, joining
Heath Shuler in 1994. Griffin was ranked 15th by his fellow players on the
NFL Top 100 Players of 2013.
2013 season After some controversy over whether Griffin would be ready for the season opener (he did not play a single preseason game), he debuted in the loss to
Philadelphia Eagles. Griffin failed to replicate his 2012 success during the first half of the 2013 season and remained statistically below expectations until Washington's Week 7 game against the
Chicago Bears. Leading the Redskins to a 45–41 victory, Griffin recorded 298 passing yards and two touchdowns, including a 45-yard touchdown pass to
Aldrick Robinson. The Redskins' 27–6 loss against the
San Francisco 49ers in Week 12 was the first game in Griffin's collegiate and professional career where he failed to score a single offensive touchdown. On December 11, head coach
Mike Shanahan announced that Griffin would be inactive for the last three games of the season and that
Kirk Cousins would finish the season as the starter. He claimed that it was done in order to eliminate risk of further injury to Griffin. He finished the 2013 season with 3,203 passing yards, 16 passing touchdowns, and 12 interceptions to go along with 86 carries for 489 rushing yards and no touchdowns.
2014 season On September 14, 2014, in Week 2 against the
Jacksonville Jaguars, Griffin was carted off the field after suffering a dislocated left ankle. X-rays and MRIs revealed no fractures in the ankle. On October 29, it was reported that Griffin was set to return against the
Minnesota Vikings in week 9. The Redskins then dropped their next three games, falling to the Vikings, Buccaneers, and 49ers. On November 25, it was reported that Griffin would be benched for
Colt McCoy, heading into Sunday's game against the Indianapolis Colts. After McCoy went down with a neck injury against the New York Giants, Griffin came in and looked impressive in a loss to the Giants, throwing for 236 yards and 1 touchdown passing. Griffin was named the starter for the rest of the year when the Redskins put Colt McCoy on
injured reserve. Griffin responded to that with a winning performance in a 27–24 victory over the Eagles. He threw for 220 yards and had one interception. In the final game of the year against the Cowboys, Griffin showed signs of his rookie year form. He threw for a season-high 336 yards and had 2 touchdowns (one passing, one rushing) in a 44–17 loss. Griffin was 2–5 as a starter in 2014 and the Redskins finished 4–12 and last place in the NFC East.
2015 season During Week 2 of preseason in a win over the
Detroit Lions, Griffin fumbled the ball and recovered it but had a defensive lineman fall on top of him. Griffin suffered a concussion in the process and was questionable for the next game against the Ravens. Griffin was medically cleared for the game by a physician, but a few days later the same physician declared Griffin not ready for the game, thus giving backup
Kirk Cousins the start. After the win over the Ravens, Cousins was named the starter for the regular-season opener and onward. On September 13, 2015, it was reported that Griffin was practicing as a safety with the
scout team. He ended up third on the quarterback
depth chart, behind Cousins and
Colt McCoy, and remained inactive for the entire regular season. On March 7, 2016, Griffin was released by the Redskins.
Cleveland Browns On March 24, 2016, Griffin signed a two-year, $15.1 million contract with the Browns. On August 8, 2016, Browns head coach
Hue Jackson named Griffin the team's starting quarterback for the 2016 season. Griffin was placed on injured reserve on September 12, after suffering a shoulder injury in the Browns' season opening loss to the Philadelphia Eagles. He was activated off injured reserve on December 9, 2016, prior to Week 14 against the Bengals. Griffin played in five games, all starts, in 2016, completing 87-of-147 passes for 886 yards with two touchdowns and three interceptions. He also rushed for 190 yards and two touchdowns. On March 10, 2017, Griffin was released by the Browns.
Baltimore Ravens After remaining a free agent for all of 2017, Griffin signed a one-year contract with the
Baltimore Ravens on April 4, 2018. On September 2, 2018, Griffin was named the team's second-string quarterback behind starter
Joe Flacco to begin the season. He was later passed over on the depth chart by rookie
Lamar Jackson. Griffin appeared in three games during the 2018 season, completing two of six passes for 21 yards. On March 21, 2019, Griffin re-signed with the Ravens on a two-year contract. On July 28, 2019, Griffin suffered a fractured thumb and was expected to miss 4–8 weeks. Griffin returned in time for the September 8, 2019, regular-season opener against the
Miami Dolphins, where Griffin came into the game in relief of Lamar Jackson toward the end of the 59–10 victory. He completed all six pass attempts for 55 yards and one touchdown. In the Week 10 game against the
Cincinnati Bengals, Griffin entered the game as a running back alongside
Mark Ingram II and Jackson in the backfield, marking what was likely the first time in NFL history three former Heisman Trophy winners lined up together in a backfield. In Week 17 against the
Pittsburgh Steelers, Griffin made his first start since the 2016 season because the Ravens secured the top seed in the AFC playoffs and sat their starters as a result. During the game, Griffin threw for 96 yards and an interception and rushed for 50 yards during the 28–10 win. Griffin was named the starter for the Ravens Week 12 matchup against the Steelers due to
Lamar Jackson testing positive for
COVID-19. He injured his left hamstring late in the second quarter of the game, but remained in until the fourth quarter, when he was sidelined and replaced by
Trace McSorley. He finished the game 7–12 for 33 yards and an interception (which was returned for a touchdown by former Browns teammate
Joe Haden) along with seven rushes for 68 yards during the 19–14 loss. He was placed on injured reserve on December 4, 2020. Griffin was waived by the Ravens on January 18, 2021. ==Career statistics==
