A couple notes or three –
First, in February and then again after the scrimmage on Saturday, Heupel emphasized our commitment to developing a 4-man pass rush. I think this is important because I think last year we were bringing a lot of the guys in the back end on blitz packages in order to augment our pass rush. It helped us set a school record for tackles for loss but sometimes it leaves us vulnerable in the back end. One writer noted that we gave up 36 3rd downs on scoring drives to our opponents last year, 33 of those were converted with a pass.
The second thing is related to our inability to run against elite run defenses as I alluded to in one of my previous posts. A few days ago Golesh speaking to the media said that our offense was going to continue to evolve. One of the media guys followed up speaking as though he was bewildered. He asked why would you want to change anything about the offense we had last year. I don’t remember exactly what Alex said but it was probably evasive.
But this is what I’ve heard. We’re adding option elements into our run game. This could be a game changer against elite defenses. jmo.
In 2011 Alabama had what some considered to be the best defense of all time. They were #1 in the nation in run defense, #1 in pass defense, #1 in total defense, and #1 in scoring defense. They were #1 in 3rd down defense and #1 in redzone defense.
That year they hosted the option oriented Georgia Southern offense (still FCS at the time). Georgia Southern rushed 39 times for 302 yards against the Tide (7.74 yards per attempt). Even including the Georgia Southern game Alabama on the year yielded only 2.43 yards per attempt on the ground or 72.15 yards/game.  
The third thing is something I’ve also mentioned before. We gave up 44 sacks last year, good for last place in the conference and 124th nationally. Heupel continues to emphasize our need to improve our pass protection across the board.
How well we do this year I think largely will depend on how much we can improve on the defensive line in regards to our pass rush, how well we can create running yards against elite defensive fronts, and how well we can protect our QB. jmo.
The one thing that is really encouraging is that our coaches aren’t trying to hide the challenges our team faces relative to our strength of schedule and they are smart, open, and honest about addressing those challenges. As a result we probably have a significant opportunity to win more games this year than might otherwise be expected. jmo.
