No one here knows the full story. You @VakAttack, etc do not have the actual details. Another "rumor" out there was Tom told Rocco they'd have a talk when he got back from Aruba and that was the final straw. @MPhillips or @RandolphTJones who are dialed in on the tOSU might laugh at that for being absurd.
I get that it's a forum and we're having fun but people are on here and other sites posting their theories as fact. I was told Rocco reached out to PSU. Is that true? Don't know and don't care enough to dig further than that
