2007 The
Cleveland Browns drafted Thomas in the first round of the
2007 NFL draft with the third overall selection. Thomas spent the draft
fishing on
Lake Michigan with his father, father-in-law, and
Joe Panos, who was also a standout offensive lineman at Wisconsin and is a former Brookfield resident. Thomas discovered he was drafted by the Browns via
cell phone. Thomas signed a six-year contract worth $43 million, $23 million guaranteed, including a voidable year, with the
Browns. Thomas won the starting left tackle job, with previous Browns left tackle
Kevin Shaffer moving to right tackle. He made his NFL debut versus the
Pittsburgh Steelers in week 1 and played every offensive snap for the Browns in 2007. Thomas quickly became one of the top-performing members of the 2007 draft class and was named the NFL's Rookie of the Month for November. Thomas was selected to the
2008 Pro Bowl, replacing
Jason Peters of the
Buffalo Bills. He was named to the NFL All-Rookie Team. Thomas came in second in the voting for
NFL Rookie of the Year. He was the only player to receive votes besides the eventual winner,
Adrian Peterson.
2008 For the second consecutive season, Thomas started each game for the Browns. Thomas was selected to his second Pro Bowl. During the 2008 campaign, the Browns offensive line only allowed 19 sacks, which was tied for the third fewest in franchise history. Thomas played in every snap during the season, though the Browns finished the season with a 4–12 record.
2009 Thomas continued his role as a reliable presence for the Browns' offensive line in the 2009 season. He started all 16 games in another Pro Bowl season. For the first time as a professional, Thomas was named as a First-team All-Pro. The Browns finished with a 5–11 record.
2010 For the fourth consecutive season, Thomas started all 16 games for the Browns. However, the Browns once again finished with a 5–11 record. Thomas earned Pro Bowl and First-team All-Pro honors once again. He was ranked 43rd by his fellow players on the
NFL Top 100 Players of 2011.
2011 On August 22, 2011, Thomas and the Browns agreed to a record setting seven-year, $84 million extension with $44 million guaranteed. On December 27, 2011, Thomas was named to his fifth straight Pro Bowl since the Browns drafted him. Since 1970, Thomas and
Richmond Webb of the
Miami Dolphins are the only NFL offensive linemen to make the Pro Bowl in each of their first five seasons. Thomas and Pro Football Hall of Fame running back Jim Brown are the only Browns players ever to be selected to the Pro Bowl for the first five seasons of their careers. Hall of Fame running back
Leroy Kelly was the last Browns player to earn five or more consecutive invitations to the Pro Bowl. For the third consecutive season, he was named as a First-team All-Pro. He was ranked 82nd by his peers on the
NFL Top 100 Players of 2012.
2012 Thomas started all 16 games for the Browns for the sixth consecutive season. However, the Browns continued to struggle with a 5–11 record. On December 26, 2012, Thomas was named to his sixth straight Pro Bowl. Thomas joined a short list of only 15 players who have made the Pro Bowl in each of their first six seasons in NFL history. He was selected for the All Pro 2nd Team by the Associated Press. He was ranked 28th by his fellow players on the
NFL Top 100 Players of 2013.
2013 Thomas continued to showcase his reliability and durability by starting all 16 games for the Browns once again. On December 27, 2013, Thomas was voted to his seventh straight Pro Bowl selection. Thomas joins Hall of Famer
Jim Brown as the only two Browns to make the Pro Bowl in their first seven seasons. Thomas on making his seventh straight Pro Bowl became one of only 11 players in NFL history to make it their first seven seasons. The list of other players who have done it and gone on to make the Hall of Fame includes
Dick Butkus,
Joe Greene,
Franco Harris,
Merlin Olsen,
Mel Renfro,
Barry Sanders,
Lawrence Taylor and
Derrick Thomas. He earned First-team All-Pro honors for the fourth time in his career. He was ranked 18th by his fellow players on the
NFL Top 100 Players of 2014.
2014 In the 2014 season, Thomas started all 16 games of the Browns' 7–9 campaign. On December 23, 2014, Thomas made NFL history, becoming the only offensive lineman to be named to the Pro Bowl in each of his first eight seasons. He earned First-team All-Pro honors for the fifth time. He was ranked 25th by his fellow players on the
NFL Top 100 Players of 2015.
2015 In the days leading up to the November 3, 2015 NFL trade deadline, the Browns and Denver Broncos held advanced talks on a deal that would have sent Thomas to Denver. Reports at the time said the Broncos offered a first-round pick, but Cleveland sought a larger return, and the sides failed to reach agreement before the deadline. Thomas later said that Broncos quarterback Peyton Manning personally called him during that period and urged him to push for a trade to Denver. Thomas was once again one of the few bright spots in a dismal 3–13 season for the Browns. He started all 16 games and earned his ninth Pro Bowl nomination and sixth First-team All-Pro nomination. At the end of the 2015 season, Thomas was named the recipient of
Pro Football Focus's
Bruce Matthews Award for best offensive lineman in the league. He was ranked 23rd by his fellow players on the
NFL Top 100 Players of 2016.
2016 For the tenth straight season, Thomas started in all 16 games. He kept his Pro Bowl streak alive in 2016 being named to his 10th straight Pro Bowl, despite the Browns finishing with a league worst 1–15 record. He was ranked 25th by his peers on the
NFL Top 100 Players of 2017.
2017 In 2017, Thomas revealed that he had been experiencing early stage memory loss, but that he would not allow it to affect his career. On September 17, 2017, Thomas played his 10,000th consecutive NFL snap, having never missed a play. He is the first player to reach the milestone in NFL history. Thomas'
iron man consecutive snap streak ended at 10,363 in Week #7 on October 22, 2017, when he injured his triceps while blocking the
Tennessee Titans'
Brian Orakpo. The next day, it was revealed that he suffered a torn triceps in his left arm, which prematurely ended his 2017 season as he was placed on injured reserve. On November 4, the Browns gave Thomas a raise in pay. On March 14, 2018, Thomas announced his retirement from the NFL. ==Legacy==
