I think that the original plan with McDermott and Beane was to build for the future; not looking to just make the playoffs and lose in the 1st round, but to plan to make and do damage in the playoffs further down the road. The Bills quick start threw a monkey wrench into that plan and McDermott, being a new HC and not wanting to lose the veterans, started preaching winning both now and later. The last three games brought everything back to reality and back to the original long term vision, hence starting Peterman. Only giving him a few days to prepare for his 1st NFL start wasn't fair to Peterman, if he is seen as a quick fix. I think McDermott thought he would play much better and could afford to stick with him. Now he has to come out on one side or the other; either try to win now with Taylor, or plan for the future and go with a rookie QB. He's in a very tough spot now.
