Jameel McClain
This Super Bowl Winner didn’t get enough credit in the Ravens’ win. Although he was surrounded by some of the best linebackers in the business at the time, McClain commanded his own end of the line, to a fault. After taking too many hits, McClain suffered some brain damage and had to stop playing football in 2014. This was not because of his brain injuries specifically, he was just cut from the Giants because of his performance.
Curtis Lofton
Lofton showed up when he was drafted to the Falcons in 2008. His best years were between 2008-11 when he played on the defensive line on the, then dominant, Atlanta Falcons. After Falcon Fever died down, he was traded to the Saints, and then finally the Raiders. In 2015, Lofton was cut, but his defensive play as a rookie solidified his place in NFL history.
