I couldn't watch the game in real time because JustinTV lags so badly, but it appeared to me that at least 50% of the time, Buffalo's DBs were 3-4 steps away from the receiver when they caught the ball. I saw that most of last year, too. That is going to give any QB time to pick his shots.
That being said, Snert's game plan is predictable, slow moving and unimaginative. Trehesitant looks awful. Without TO as a safety valve, he seems afraid to throw the ball any farther than 10 yards. He's starting to look like his confidence is gone. The combination of Snert & Trehesitant is lethal.
