I will go out on a limb here and guess that we are going in the right direction. One of the problems with the Urban Meyer spread is that he sacrificed size for speed at RB and WR in order to get that misdirection. This is similar to what Steve Spurrier did with his Fun N' Gun. We got manhandled by teams like Nebraska because no matter how fast we were, we were getting dominated in the trenches. Under Spurrier, we had the fastest team in the Galaxy and we could stretch the field vertically...if the WR survived the bump and run. Under Meyer, we had the fastest team in the Galaxy and we could spread the field horizontally...if the QB and RBs survived first contact.
I have read through the play books of a typical Ernhardt-Perkins offense that will be used by Weis, and I as an armchair QB can see that the boys will probably do well once Weis has a couple recruiting classes under him to get bigger RBs, and maybe a different style of TE. Would Briskett fit better than Driskel in this offense? On paper, yes. In reality, I really think we are going to be pleasantly surprised by Driskel and Briskett will go elsewhere and probably do very well there.
What we have to hope for is that Weis' offense does not repeat the mistakes of his predecessors--keep the speed, but keep the size as well.
Just as an example. Meyer's first NC running back was DeShawn Wynn at 5'10", 230 lbs. His second NC running back was arguably Tim Tebow at 6'3", 240 lbs. Neither Rainey nor Demps break 200 lbs. Maybe they will be a part of the 2011 Gator rushing attack, but watch for these scatbacks to give way to powerbacks sharing the backfield with the scatbacks (as Weis did in Kansas City). As we grow bigger RBs, I think we will see better passing from Driskel and forget about Briskett...definitely Brantley (unless he surprises the heck out of all of us).
