Couple things...he's making $1.1 million here...he's not leaving for 1.3,4 or 5 is he? By all accounts his family is entrenched in the Twin Cities. AND, do we really think if friction in relationships is not the reason, you think Coyle wouldn't approve $200, 300, 400K to keep him?
I don't think it is money.
I could see the offense being so bad that it effects defensive performance being a reason but just PJ and Rossi at odds seems most likely to me.
I guess there is the possibility he could see the future schedules and be wondering if we'll be able to compete and just getting out while he can. New job is likely couple years of security...2 or 3 year contract to leave?
