Shockey has publically acknowleged being on anti-depressant type meds. Don't have link - someone else can Google if they really want to - but I remember an SI article about him back during the SB run.
Ingram is still pissed about being in Cam's shadow - 2010 should have been HIS big year, and instead, Cam took all the spotlight, kicked his ass in the Iron Bowl, won the SEC and the BCS, THEN to add insult to injury, was first pick in the draft. In Ingram's mind, he is still trying to prove something - and there's no way in hell he ever will top Cam. EVERYBODY knows who Cam is - only Saints fans and bammer turds know who Ingram is.
