Green Bay Packers In 1999, Brooks began his career as a third-string backup to
Brett Favre behind second-string quarterback
Matt Hasselbeck, taking no snaps during the regular season.
New Orleans Saints The Packers traded Brooks and tight end
Lamont Hall to the
New Orleans Saints for linebacker
K. D. Williams and the Saints' third round pick in the
2001 draft ahead of the 2000 season. In his first season with the Saints, Brooks took over as starting quarterback after
Jeff Blake was sidelined with a broken foot in the team's 11th game of the season. In his first NFL start, Brooks led the Saints to a 31–24 victory over the
St. Louis Rams, becoming the first QB in NFL history to defeat the defending
Super Bowl champions on the road in his first career start. Brooks led the team to a 3–2 record in his five starts for an overall 10–6 record, winning the
NFC West. In the playoffs, the Saints defeated the Rams, 31–28. The Saints were without their starting running back,
Ricky Williams, and lost their best receiver,
Joe Horn, early in the game. Brooks threw four touchdown passes to lead the Saints to their first playoff win in franchise history, becoming the first QB in NFL history to eliminate the defending Super Bowl champions in his first career postseason start. The Saints then lost their Divisional Playoff game to the
Minnesota Vikings, 34–16. In 2001, the Saints went 7–9, ending on a four-game losing streak. In those last four games of the season, the Saints would be outscored by more than 100 points, 160–52. Brooks threw a then franchise record-tying 26 touchdowns and a career best 3,832 passing yards in his first full season as a starting quarterback; he also threw a then-franchise record 22 interceptions. In 2002, Brooks lead the Saints to a 6–2 record and guided an offense that averaged 32 points a game through the first half of the season before the team imploded in the second half. The Saints went 3–5 to finish the season, losing their last three games to teams eliminated from playoff contention. 2003 was Brooks' most efficient year, compiling an 88.8
passer rating, a 3:1 touchdown to interception ratio, and a 59.1% completion rate, all career bests. However, the Saints finished 8–8 and did not make the playoffs. In 2004, the Saints started 4–8, but finished the season with a four-game winning streak. The Saints almost made the playoffs but lost out on tiebreakers. Brooks threw 16 interceptions that year, twice as many interceptions as the previous year. 2004 was also the final year Brooks threw for more than 3,000 yards (2,743 meters) in a season. In late 2005, after losing to the Falcons, the Saints benched Brooks and announced
Todd Bouman as the team's starter for the last three games of the season. Brooks finished the year with 17 interceptions to 13 touchdowns.
Oakland Raiders After being released by the Saints, Brooks was signed by the
Oakland Raiders in March 2006. He was the starter going into training camp. In his first regular season game as a Raider, he was sacked 9 times by the San Diego Chargers in a 27–0 loss. Brooks dislocated his shoulder in his second game against the
Baltimore Ravens and missed the next several weeks. Second-year quarterback
Andrew Walter started the next seven games for Oakland. After a 2–5 record over that span, a healthy Brooks was placed back into the starter's role. Despite slightly improved play, Brooks was unable to lead the defensive Raiders to very much success finishing with a league worst 2–14 record. Brooks also went on to have a career low 61.7 quarterback rating, and again threw more interceptions, eight, than touchdowns, three. Brooks was released by the Raiders when they did not pick up his option after the 2006 season. ==Career statistics==
