Manning/Brady establishing culture? What you meant to say is in a league where so much hinges on the success of the QB, when you have a good one, everyone dials in.
What happened to the Cavaliers culture of being pure garbage when they got a **** load of talent? What about the Miami heat culture that came and left with some of the league's top talent?
Its so damn easy. When you have the talent to win, chances are everyone will buy in and simply put, try harder. Stop trying to be old timer farts with this - its a game, the people who are better at the game win 98% of the time.
