Coaches, whether they be position coaches or coordinators or even head coaches, typically have a primary basic philosophy that they prefer and, if possible, work off of in their coaching. This philosophy is almost always either offensive or defensive. Coaches also typically have specialties, i.e. certain tactics or positions within that unit that they are very particular about. Head coaches will typically be heavily involved in, if not completely controlling, the coordination of the offense or defense, depending on their philosophy. Head coaches will often directly coach the position(s) that are a part of their specialty(ies), with and/or without an additional position coach. When it comes to the counterpart unit, e.g., the offense for a defensive minded coach, the head coaches' approach will usually fall somewhere between a janitor role and a general manager role. The janitor role means that he doesn't really do anything regarding the design and administration of the unit but will lend a hand when needed and clean up any messes left behind. The general manager role means that he dictates the overall philosophy(ies), goals, individual responsibilities, etc. for the units coaches but leaves the details up to the coaches. Very rarely will a head coach perform "coordinator" responsibilities for both the offensive and the defensive units. For example, Coach Saban is a defensive coach who plays the general manager role when it comes to the offense; he calls the plays for the defense while allowing the OC to call plays for the offense while reserving the right to overrule the OC if he desires. Mike Leach played more of the janitor role when it came to defense; he called the plays for the offense while leaving virtually all play-calling duties to the DC, often paying seemingly little to no attention to what was happening on the field with his defense.
Coach Saban is primarily a defensive minded coach. His primary basic philosophy revolves around defensive pressure. His specialty is in the defensive backfield, particularly coverage and blitz schemes. He dictates that his offense will follow a certain philosophy with certain goals in order to complement his defense.
So, in this vein, where does Sumlin fall? He's definitely an offensive minded coach. It seems that his primary basic philosophy revolves around the passing game. His specialty seems to be working with the receivers. Short of whatever Sumlin himself has publicly revealed about his coaching philosophies we really don't have much to go on. He's only been fully in control of an offense for four years now, all with Houston. Before that he was a Co-Offensive Coordinator and Receivers Coach at Oklahoma for a couple years but he wasn't the one primarily devising the game plans nor the one calling the plays. For the three years before that, at Oklahoma, he was coaching the Special Teams and Tight Ends. Prior to that he was the OC at Texas A&M for R.C. Slocum's final two years. Of course, we all know that R.C. wasn't anywhere close to giving Sumlin free reign of the offense. Up until that point he had only been a Receivers and/or Quarterback coach at a few other schools.
For that reason, again aside from anything Sumlin himself has said, all we have to go on regarding what Sumlin wants to do offensively is the last four years at Houston.
uafan4life, I think we will be closer to 50/50, maybe leaning more to the pass. It really depends on what the defenses show us. QB will be key since he has to read the defense very quickly, keep things moving. I think we will be a lot like the OU offense when Sumlin was an OC a few years ago. OU had a lot of talent and Sumlin used all his weapons. At UofH, Sumlin's talent pool was limited and he made the best with what he could recruit. Mike Leach did the same at tech. A&M's recruiting has been slightly behind texas and ou. Now that we are in the SEC, recruiting will start going in our favor with the best players in Texas that want to play with the big boys. We are also making inroads in Louisiana. Lsu is the only big time school in La. and they can't take all of them. Louisiana has some good football players and A&M is another strong option for them.
Pace will be fast, we will try to run 80+ plays per game and won't allow defenses much time to set up.
When we play y'all, I expect Saban to eat the clock, run it up the middle and wear out our DL and LBs.
We'll see what happens. I'm looking forward to it. I don't expect to beat Bama or lsu, but we won't lay down either. In two years, if recruiting goes the way I think it will, we'll be right there with you guys. It's going to be fun.
Looking at the last four years at Houston it seems that Sumlin's desired run to pass ratio is anything but balanced, leaning heavily towards the passing game, while his preference for an up-tempo pace seems to very consistent. I've posted a table below with the individual numbers and averages for those four years. There is an oddity in there, though, in the form of the 2010 season. While his offensive pace was still very much up-tempo it was slightly less so than the other three years. The Pass/Run Balance, however, is where the real disparity lies as it leaned much, much heavier to the rushing side than the other three years. The reason for this disparity? I'd say the fact that he lost his top two quarterbacks for the season in only the third game of the year had something to do with that.

For that reason I've added two averages columns instead of one; one averages column shows the averages for all four years and a second one shows the averages for the three years besides 2010 which I believe more accurately represents what he wanted to do offensively while at Houston.
I'd say that you're dead-on with the 80 plays a game target as that falls perfectly in line with what he did at Houston. However, I'm really puzzled by the notion that the pass/run balance will be close to 50/50 given the numbers from his time at Houston which was, again, the only time he was ever in full control of an offense.
I know that he'll have some pretty good running backs at A&M and will want to utilize them. However, I think he wants to use them a lot more as receivers and a lot less between the tackles than most other offensive coaches. Heck, even in the year where he had to play his 3rd and 4th string quarterbacks for nine and a half games he was still leaning heavily to the pass in his play-calling. In the years that he seemingly able to do what he wanted he threw the ball over 60% of the time. It's a pretty major paradigm shift to go from an offensive philosophy that tries to throw the ball almost two-thirds of the time to one that tries to maintain and even balance between passing and rushing.
What exactly makes you think that he'll more or less completely change his offensive philosophy?
EDIT: Spring Game Info...
After having finished this post initially I decided to take a look at the numbers from the Texas A&M Spring game. Now I know the starting RB was out for the game (just like ours, btw) and so that could affect the numbers a little bit. It is also a spring scrimmage and so the play-calling is likely to not be exactly as it would be in a real game in the fall. However, you would expect the overall philosophy and general tempo and play-calling tendencies to be pretty close. The Aggie spring game seems a little odd in that the White Team outscored the Maroon Team 48 to 44 but the White Team is listed as the offense and the Maroon Team is listed as the defense. (By the way, I'd like to watch the game but couldn't find it last night on ESPN3. Do any of you know where I can watch it online?) Since all of the offensive stats are lumped together I thought that I would look at it as cumulative stats from two games and divide the numbers in half to get an "average". However, those numbers didn't seem right. I got these numbers from the
aggieathletics website but there's something very odd going on. For example, the article accompanying the stats says that the offenses combined ran a total of 105 plays in the first half. However, the numbers at the bottom only total 107 plays. How were they counting plays? Were there only two plays run in the second half? I'm also curious as to whether there was extensive situational work such as two-minute or red-zone offense. Anyway, here are the numbers I found:
