Wow, you're really overrating the 300-yard stat. Cutler took 52 attempts to get there, so his YPA was a paltry 5.9. He also threw five picks, two in the end zone, in a game that saw his much-maligned defense deliver a great performance. Did Cutler have a running game? No. But he did have a solid TE in Greg Olsen and a capable WR in Hester, who's on pace for over 80 catches this season. There's no justification for a five-interception performance. The 49ers tried to give that game to the Bears, but Cutler kept giving it right back until time expired.
There's a difference between a gunslinger and a guy who just throws it up for grabs, which is what Cutler does. How else would he be on pace for 34 interceptions?
Bottom line, I don't want him anywhere near the Bills. You'll get flashes of brilliance one week and what we saw against San Francisco the next. He's nothing more than a slightly better, much more hyped Losman.
