Aaron Brooks
Midway through his second season in the NFL, backup quarterback Aaron Brooks took over for incumbent starter Jeff Blake, and led the New Orleans Saints claimed a spot in the 2000 playoffs. Brooks and the Saints took on the St. Louis Rams, who were the defending Super Bowl champions at the time. Brooks threw four touchdown passes in the game, becoming the first QB in NFL history to eliminate the defending Super Bowl champions in his first career postseason start. After being eliminated from the postseason in the following week, Brooks never made another playoff appearance.
He wasn’t nearly as good in the next two seasons, and the Saints eventually benched him for Todd Bouman. Brooks signed with the Raiders the following season but managed just 3 touchdowns and 11 turnovers in his 8 starts. Brooks, only 30-years old at the time, never played another NFL game.
