I'm an eternal optimist, I just don't see the value in pessimism. Last year the Bills finished 8-8 with a new coach, which brings new systems. There was also a new QB. This year is year two for all, a consistency the Bills have lacked. So the reason that people think they will finish the same, or worse is injury. Lost for the season is a rookie LB and a second or third string TE that a few months ago many thought may not make the team. Lost for some games, pro bowl DL man and rookie LB.
All teams have some weaknesses. The Bills have talent, their weakness is depth at some positions, namely OL, LB and TE. We have watched Bills teams win six games with bad coaching, no QB and serious lack of talent at skill positions. Which is why I don't get the 6-10 crowd. What is the same finish as last year based on? Mario Williams being gone? For all intents and purposes he was gone last year. Some point to the schedule, but every year there are teams that are supposed to be good that aren't and vise versa.
Perhaps it all comes down to whether one things Ryan can coach, we shall see.
