13. Donavon McNabb
Statistically, McNabb had one of the best seasons of his career in 2009. However, the numbers don’t always tell the whole story. Coach Andy Reid decided that he had seen enough and that at the age of 33, McNabb was on the decline. It seemed ruthless because McNabb went to the Super Bowl with him and knew no other coach.
Nonetheless, the Eagles traded McNabb to the Washington Redskins. Then he spent the season feuding with Mike Shanahan, who dropped him twice. After a weird year in the capital, they moved him on to Minnesota. After a 1-5 start, the Vikings benched him and he never started another game in the NFL.
