Look at the stats for that game - the Bills outgained the Raiders through the air and on the ground, and still lost 34-13? McFadden was held to 28 yards, and the whole team averaged about 3 yards per play (compared to over six for the Bills). And, had Janikowski not missed two field goals, we would have given up 40 points?
It's a video game - did it just get stuck on "fumble" at the end of every Bills' play?
