Up against the top point-getter in my fantasy league

My Fantasy Football League: I'm up against the top point-getter in my UPC Hood Fantasy Football League today. The A-Team has Mr. Brees and Mr. Rivers. I have a couple of average run-of-the-mill guys in Fitzpatrick and Grossman. I decided to go with Grossman over Orton. That could be a mistake, but if Orton has a bad first quarter and the Bronco fans start yelling for Tim Tebow...then I'm sunk anyway. Need big games from Mendenhall, Charles and Benson to have a shot at Week 2.
