Khalil Mack
Mack was one of the NFL’s top defensive players for four years but that feels like a long time ago now. The Chargers thought that they made a genius move when they nabbed him from the Bears. But he has yet to prove that he is the same Pro Bowl star he was during his prime years.

People still talk about him as if he’s a potential MVP but the reality is that he’s not at that level right now. Sure, he’s found himself in tricky situations but his production dipped in Chicago. He had better individual seasons than his entire career in the Windy City. It’s a shame because he was a magnificent talent but he doesn’t seem as good now (via Fansided).
