I can only respond to what I know about Alabama, because I've only seen Texas play maybe three times in the OU/A&M/Neb games;
1. Our defense is overall improved, more talented, and faster than last year, and we've faced the spread in a few games already this season, so toss the Utah game last year out the window, it doesn't mean anything this year.
Our linebackers are big and athletic & move really well side to side across the field. Ex.Rolando McClain moved across & chased down UF's Demps (world class sprinter) & prevented him from making the corner in the SECCG. Anders and Reamer will bring pressure as well. The mismatches occur when one of these guys get caught out of position and have to cover a wide receiver downfield which happened on one of UF"s big plays. But it doesn't happen often because BAMA plays very disciplined defense.
As good as our defense was last year this one is a lot better, especially in the secondary where it struggled at times last year against spread teams. Our D-line is much improved & while I epect Cody to play (he's our hole clogger in the middle), Texas will probably see just as much of Marcel Dareus who can & will bring pressure.
Another year in CNS system has made the difference in all areas.
This BAMA team is different on both sides. Mark Barron is young, but talented ball-hawker, Arenas is starting at CB (he does more than return kicks) he like all of our secondary will challenge everything which was not always the case last year.
2. Conditioning. I only remember one game all year that BAMA's defense showed any signs of fatigue and that was UTee which was a slobber-knocker slugfest fight-to-the-end game.
Alabama is extremely well conditioned and stays strong in the 4th quarter. As someone mentioned, we rotate our linemen/linebackers thru-out the game defensivley, and offensively also run several running backs, and typically go with the hot one early. Its not just Ingram, but also Richardson, and Upchurch. We'll also play several tight ends.
3. Florida's defense as opposed to Texas defense.
UF has speed all over the field and lots of it, and to say UT's is that much better or faster or that Alabama hasn't faced one as good, is bit of a stretch. Florida's defense ranked #1 up until Alabama beat them.
Not disrespecting UT's defense but to say Alabama hasn't faced a speedy defense like UT's all year is ridiculous statement as there are several teams in the SEC that have lots of defensive speed, LSU, Ole Miss, UT and UF come to mind, and I'd put VaTechs defense in there too. LSU has a ton of speed and may have one of the best corners anywhere in Patterson. He's one of the best I've seen. Berry at UTee is another. LSU & UF would both compare to UT, imho.
And I don't remember Florida or Alabama's defense giving up 39 points to a 6-6 team all year, although I believe Ole Miss & UTee both had a game that was similar score wise.
Just some thoughts on the subject.
I would also add I have great respect for the Texas program, and almost to a fan, when asked who we wanted to play in the NCG, it was Texas. No one here disrespects Texas and most understand its not easy going undefeated in any conference. I think TCU may be one of the best teams out there as well although I'm not sold on Cinci or Boise St being in the same league.
Either way, its going to be a great matchup with two very good teams. I think McCoy is one of the best qbs playing in college football, and hopefully we'll be able to stymie the McCoy to Shipley plays and keep them to a minimum. Shipley reminds me of Riley Cooper at UF, he just makes plays, and is hard to stop. So that is one of my biggest concerns as a BAMA fan, in this game. The other concerns are will our Oline and the running game be able to have success, as UT's defensive strength lies in stopping the run.
