The Jets have alot of toys on offense this year, Dansby is a much needed upgrade for us, but like junc said, I'm not sure he can take Keller out of the game. He is going to need safety help over the top for sure, Keller is closer to being a WR than a TE.
With Edwards, Holmes (yea, he will be suspended for the first meeting), Keller, Cotchery (Coles was released yesterday I see), and LT who is no slouch at catching balls out of the backfield, our secondary will have its hands full.
The real questionmark is Sanchez. As mentioned earlier, will he try to force throws into coverage? If so, I like our chances. If he is smart about it and his O-line (which is far from shabby) gives him time, those guys will get open eventually.
So the other nagging question is really whther or not our pass rush will be enough to force mistakes. I'm not sure we will know for another two weeks, as it seems the team is sitting on some kind of secret and we arent going to let anyone know about it until the season starts....
