I bet he is just pissed that he has become a laughing stock. I would imagine he has been hearing all week smack talk at the combine about -
1) 30 years
2) His terrible last 2 4th round trades and how they are handicapped the team come drafttime.
3) His ineptitude and managing the cap. When other teams can manipulate it so we'll.
4) He does not like playing defense, and probably bristles at the thought of everyone bagging on him.
5) The Samuel's deal for a 5th, shows how bad a negotiator he is - 4th for Mingo, 4th for Lance.
I would hazard a guess he's just thoughly mad at the world right now and left.
I thought he had announced he would speak on Thursday, so something changed.
Or, he's finally doing his job with our free agents : )
