I don't understand the fascination with the 300 yard game. I would prefer that no Buffalo QB ever throws for 300 yards. It's usually a sign that you've been forced to abandon your running game due to a deficit.
The ideal game for a quarterback involves efficiency, not total yardage. Trent had a very good yard per attempt, didn't make any mistakes and had a very efficient day in general, something which his QB rating reflects. How would throwing for a 300 yards have been an improvement on his performance?
Drew Brees consistently has "the big game", and they're not having any better of a season than us. 300 yard games for a QB occur when you've got a really really bad defense, or when your game plan is dominated by the pass. Two of our best players are our RBs, and as long as Lynch and Jackson are around, our offensive game plan should be 50% run, 50% pass.
