2. Curtis Lofton, LB (2012)
Well, this is one that hurt a lot of Atlanta Falcons fans because Curtis Lofton went on to play for the New Orleans Saints which is never a good thing.
Lofton was a second-round pick for the Falcons and he only ended up playing four seasons with them. His rookie year was his only time not recording over 100 tackles with the birds and when he moved on to play with the Saints, he ended up having three more seasons with triple-digit tackles.
If Lofton hadn't signed with New Orleans then he might not have made this list. Having success after joining a division rival makes it hurt a lot worse.
