On the HUNH I'll just add this...
Saban hinted at the real problem this presents in the post-BCSNCG show, where he talked about how the HU with a quick snap virtually eliminates a defense's ability to stem and give multiple looks pre-snap. You just don't have time to do it, because you have to scramble like hell just to get lined up properly, and the ball gets snapped immediately. For all that has been discussed over the years about how the multiple looks from Saban's 3-4 defense gives opposing offenses a hard time, an offense basically eliminates that concern entirely with the HU and the quick snap. In hindsight, it's really a surprise that OC's didn't seize on this a lot sooner than they did, although now it has essentially become the status quo.
That notwithstanding, though, we really haven't had a major issue stopping the HUNH itself, as opposed to just stopping good passing games. If you look at how we played against the two of the three biggest SEC proponents of the HUNH -- Auburn and Ole Miss -- we actually fared relatively well, despite a few major discipline-based breakdowns in the Iron Bowl. The bigger issue we had was that any time we played a team with an above-average pass game, we were just eaten alive. That's really the issue we had against A&M. We did well enough, relatively speaking, against the hurry-up, but Manziel rained bombs on us all day through the air like a video game trailer.
I posted this on the recruiting board yesterday, but will reiterate here in this forum. Against the three best passing teams we faced all season -- A&M, LSU, and Oklahoma -- we gave up a combined 76-106 for 1053 yards, 10 touchdowns, and 3 interceptions. That's a 71.6% completion percentage, 13.8 yards per completion, 9.9 yards per attempt, all with a better than 3-to-1 touchdown-to-interception ratio. That's not quite 2001-type bad in terms of pass defense, but it's dangerously close, and that's more of a personnel and scheme issue than anything else. As long as we have a non-existent pass rush mixed together with bad cornerback play -- not to mention safeties routinely isolated on wide receivers due to the lack of quality CB depth -- we are going to get lit up by quality passing games, and those teams will convert third-and-long like most teams convert third-and-two.
My point here is that I think we will be fine in time against the HUNH itself, even though that obviously does cause some substitution and pre-snap alignment issues. That non-existent pass rush and bad CB play, though, we are really going to have to go back to the drawing board on our own end. It may very well be time for a pretty big revamp defensively in terms of personnel types and recruiting strategy.
