This is where Marv's age comes into play, which will be a huge bonus for Buffalo. I agree that teams will try to push him around. Yet Marv will just think to himself, "do you know what I've been through?" He is also a master psychologist. He will let the other GM's think they have the best of him, and when their guards are down, suggest something that they'll be more likely to accept, and then we'll be all praising the values of Marv as a GM.
