If you want proof of his homerism look at his record picking Saints games (24th) on this site that tracks the talking heads. Now look at his placement picking Panther games (80th) and you can tell he picks (hopes!) the Panthers will lose every week. Note that he is 17th predicting falcon games because they both suck.
One thing you have to understand is Sean is as much a Cam Newton homer as Heath Evans is a Saints homer. Sean had Cam for MVP before the season started and has picked us to make the playoffs the past 2, maybe 3 seasons. He picked Cam for Rookie of the Year before any games were played. Sean absolutely loves Cam. I think he feels a connection to him being a black QB in the NFC South.
