8. Aaron Hernandez
We’re not going near the Aaron Hernandez murders, and because he was such a bad teammate we don’t even need to. As a Patriot he was known to be a bit menacing and unstable around the practice facilities.
Wes Welker gave, then rookie, Hernandez some light ribbing to which Hernandez responded by shouting, “f— you Wes, I’ll f— you up!” Surely they stayed away from the traditional rookie hazing pranks after that incident.
