Fisher's only real mistake was not being decisive with either benching or supporting Vince. Really that is what created a lot of the controversy. On the other hand though, I believe that Fisher wanted to definitively bench Vince but Bud Adams loved Vince and wouldn't let him. Bud cut Fisher's legs out from under him in the VY situation. The owner had his back and Vince used it to his advantage. Why listen to a coach you don't like when the man who cuts the checks loves you and will take your side? It takes a lot of character and maturity to not take advantage of a situation like that and Vince just didn't have it at the time.
