For me, it's like this and like that and like this and a....
A few points:
Sean White is the best all around QB we have. But he is severely limited in this offense. He's got decent wheels and can take off a few times when the pocket breaks down. But he is not a read option QB. Circa 09' Gus.
If Malzahn stubbornly refuses to adjust his O to fit Sean and continues with the same thing Nick Marshall was running, then put Clifford Franklin IV in. I don't like and don't want CFXXV as our QB, but if it's the read option, then he's the only choice. Or Woody Barrett.
If at this point, you have any QB on your roster that's "Still learning the offense", then you either suck as a coach or you recruited a bunch of Down Syndrome kids. When the opposing team is laughing at you and openly telling the world you only run two plays...there's a problem. A big one!
