You had an obligation to stir up a huge s-strorm over this as soon as he changed his mind on the deal, as to leave him 2 options: proceed on the deal, or re-do all the auctions after the MJD transaction. Your storm was apparently not of significant enough proportions, and now with the 1 blow up week, even if you are being honest (and I believe you are) it's going to LOOK like your motivation is based off of last week's performance.
I wouldn't play in a league with a commish that would do that. If it's no money, I'd probably leave the league. If it's money, it'd be my last season. But I know it would not have been possible to cool me off into week 1 with a roster that doesn't reflect a deal that was agreed on.
