The odds were stacked against VY in Buffalo. He is not a backup QB. He either starts, finds another team or is out of football. It was made clear to him that he was competing with Thigpen for a backup job and not competing with Fitz for the starter's role. He was also being asked to adapt to an offence specifically designed by Chan for Fitz and which did not cater to his strengths. He also came with some personal baggage that everyone, especially him, could have done without.
It was maybe asking too much of the Bills to do what would have been necessary to get the most out of VY. They would have had to make it an open QB competition and tailor the offence to his skills to some extent. Having a legitimate shot to resurrect his career might have helped turn things around for him. But then what would have happened to Fitz's blessed confidence.
Vince Young, Tarvaris Jackson...I'm getting just a little fed up with Chan and his impossible to digest play book.
