I readily acknowledge that it is impossible to measure the "impact" that home fans have on any game. After all, it doesn't matter where the game is being played or how many fans are there -- players need to execute, and they need to perform no matter how favorable / hostile the environment is.
But that said, the notion that fans have "zero effect" on the game is asinine.
Hell, we've seen it when SU has been on the receiving end [like when the GT fans got on Gillon, vociferously chanting "AIRBALL" every time he touched the ball]. It got in his head, and he had a poor outing -- clearly he was affected by it]. We've seen visiting players [like QBs] unable to hear at times, affected by crowd noise -- and had the same thing happen to OUR team when we've been on the road, at various times.
And I've seen times where the crowd is so off-the-hook in the Dome that it clearly affects the opposing team. To say nothing of how the players often seem to feed off the energy of the home crowd, or what opposing coaches have to do to counter the noise / energy in the building ["better get a TO"].
So to say it has "zero effect" is a h0t t@ke, at best.
