I think a wet field can actually favor the pass game. It's easier for a receiver to keep his footing because he knows where he's going. A defender doesn't know the route and has to quickly react, which makes him more likely to slip. Plus, Joe has the arm to zip passes through any weather conditions. I don't think we'll have to rely on the run, but if we did, I have no doubt that our RBs are good enough. They have both showed good burst and power. It's the run blocking that I'd be concerned with. The O-line has shown recently that they can pass protect for an entire game, at least when we speed up the tempo and get rid of the ball quickly, but they haven't been able to consistently open up holes in the run game all year.
Also, the Partiots defense is the worst against the pass. When teams come gunning for them trying to be balanced, they loose. When they open it up against them, then the Patriots suffer. You are totally right about the weather and what works. The Viks Ravens game was a textbook for that, defense suffers trying to cover and adujst to speed guys. Watchout for Kraft manipulating the TV timeouts again....
