There's plenty of reason for people to be optimistic. Nothing crazy about that. I have very big doubts, but remain hopeful he can get the job done. obviously, we know very little about the man in terms of contemporary, 11-man football. it could really go either way, and drastically. See, I don't think it will be that drastic either way. I think in the NFL games are won by players, schemes, and playcalling. Most of the players from a 10-win team are back. Granted, the guys on D are a year older, but they actually got younger (going away from Urlacher and Idonije) and guys like Tillman, Jennings, and Briggs are coming off at or near the best seasons of their careers. The dropoff doesn't happen that fast without injury (which obviously could happen). As for schemes and playcalling, that's supposedly where Trestman excels. Granted that's in question because it has been 10 years since he has done either at the NFL level, but it's going to be hard NOT to improve over the last 3 years in both of those aspects. The key will be how much better the playcalling and schemes are on the offensive side of the ball vs. how much worse they are on the defensive side. But the defense is where the "players" still are for this team.
