In 2003, the Chicago Bears had two first-round picks, No. 14 and No. 22. With the first of those two, they selected Haynes out of Penn State, with the other they grabbed quarterback Rex Grossman.
Grossman led the Bears to the Super Bowl in 2006 and by that time, Haynes was already out of football. The defensive end recorded two sacks in 16 games as a rookie, and after just three seasons with the Bears was cut in the 2006 preseason.
Haynes was signed by the Saints in 2006, but was made inactive and never played a game for New Orleans. He finished his NFL career with 5.5 sacks in three seasons.
