Stoops deserves respect, for sure, and they should be good on both lines, they have a good stable of RBs, and supposedly solid in the LB corp. But UK has not really been that good at WR under Stoops, and not really sure their secondary is more than average JG shredded their secondary in one half last season.
Having said that, UT also should be very good on both lines, also has a good stable of RBs, and should also be pretty darn good at LB. At WR, While we should be very good at WR this season, admittedly it is a bit of a question mark with the loss of Calloway and JJ, but we definitely have some talent at that position. And I know UT is better in the secondary.
So the x factor for both is at the QB position.
