1. Sean Lee
The Dallas Cowboys’ best defensive player, Lee was lost to a torn ACL during OTAs. And it’s a major blow to an already terrible defense.
Now Lee is being replaced by one of the biggest defensive busts in recent memory, Rolando McClain, who has come out of retirement to try and fill Lee’s shoes. The task is too great, and the loss of Lee could result in Dallas picking in the top five in the 2015 NFL Draft.
