I see no reason for Polian to be mad at Doug Maronne. If he's mad at anyone, isn't it far more likely the people who were bad mouthing him?
also not sure how Doug has been "bashing" the bills. I haven't followed every story so could be wrong, but it seems to all stem from that original story about Doug telling his friend, in confidence, that some of the Bills front office were "bad mouthing" him. Which some writers decided to make more exciting by describing as doug "bashing" the bills. Which other writers parroted enough that it became truth-y.
