Somebody will figure a way to at least slow him down...maybe. I was listening to some local sports talk this morning and they were discussing that very thing. They used the example of Troy playing MTSU a few weeks ago and employing the same approach as Bama did with Tebow last year. MTSU had Dasher, the do everything QB back and Troy basically had their D-lineman stalemate the O-line and don't force the QB's hand. Bama did the same to Tebow in that they pushed hard straight ahead but never "Went beyond" him in an effort to contain him.
In other words, pretty much hold your ground and force him to throw it. If that can be done, and that's a huge if, that may be the only way to slow him down. I recall Arky positioning their ends a bit wider, trying to funnel him into runs up the middle, but that wound up playing right into his strength. Ask #31 about that.
The only way I think you can stop him is to let Cam be your main focus. Have the end crash down every time on the option play and force Cam to hand the ball off. Other wise, you are going to have a single defender on Cam trying to make a one on one stop. That ain't happening.
I think our OL is too good to let a defense just "stand their ground". That shit aint happening. If the defense doesn't try and get a good push up front, they are going to get blown the fuck back. If that happens, Cam, or Dyer, or however, will gain about 5 yards at least a play.
I think the only way to slow Cam down is to play a base zone defense and not blitz. But then again, I am not sure that would work. I don't know what the fuck you do really...every option team I have seen that has a good running QB is tough. Cam is a fucking EXCELLENT runner so it is nearly impossible to stop. I would make Dyer and McCalleb beat me. I would crash on Cam from play one...with multiple guys. I guess...the thing is, those other guys can and will beat you too...
