Nope.
1) The Broncos almost never throw seam routes anymore.
2) Thomas and Sanders cause problems for everyone.
3) Vernon Davis should be pretty good in that offense, but am I worried about losing a game because of Vernon Davis? No.
4) Daniels and Hillman are absolute JAGs, and I'm not really sure why I should be afraid of them.
Also, the Broncos have no one who can cover Gronkowski. Or Lewis. Or Chandler in the red zone. Nobody. Talib and Harris are good players, but I'm not as concerned, since the Patriots aren't going to be running go routes and 30-yard outs all night like the Packers did.
