20. David Carr (2002, Pick #2)
Throughout the 2001 college football season, there was no question that defensive end Julius Peppers from the University of North Carolina was the best player in the nation, and should be the #1 pick in the NFL Draft. But as the draft process approached, quarterback David Carr began shooting up the draft boards, and ended up being taken by the expansion Houston Texans in the 2002 NFL Draft.
Carr would spend his career in Houston getting absolutely battered behind a terrible offensive line, while Peppers thrived for the Carolina Panthers, who took him one pick after Carr (#2 overall), finishing with double-digit sacks six times during his eight years in Carolina.
