There's a long list of OCs whose styles haven't meshed well with Saban's, that's about all I'll say about that.
He was an offensive assistant and sort of a co-OC at Texas for a few years, then he was the sole OC in Mack Brown's final year here. The wheels had long since come off that wagon, so it wasn't really much of a role.
Mostly I really liked what Applewhite's offenses under Tom Herman looked like at Houston-- they were far, far better than what Tom Herman has fielded at Texas thus far, and with mostly inferior athletes to what we have on campus in Austin. Our current OC is a bit of a lost cause. Watching him run Sam Ehlinger directly into the center of Georgia's defense 5 times in a row right at the goal line was mind-boggling and depressing. It eventually worked simply because Ehlinger is a badass, but it was horrifyingly awful play-calling. And we get that type of thing a lot with our current OC.
saban gets a bad rap with his offenses, i guess because he's known for his stellar defenses.
but he's put out some great offenses (or allowed his oc to do so, however you want to look at it).
his offenses produced 2 of the top 5 all time passers for a season for lsu (and recruited and coached a 3rd before leaving for nfl) (all diff players), 6 top 10 career and 3 of top 6 single season receivers.
at msu, he had 1 top 10 career passer, 2 top 10 career rushers, and 2 top 10 career receivers.
at bama he has 3 top 5 and 5 top 10 career passers,
9 of the top 10 single season passer records (7 diff players), 2 top 5 and 6 top 10 career rushers, 3 top 5 and 6 top 10 single season rushers (6 diff players), 3 top 5 and 5 top 10 (could be 7 if you count 2 sr in his first year) receivers career, and
9 of the top 10 single seasons receiving (6 diff players).
granted none of these teams were ever really juggernauts on offense, mostly building their reps on d, but saban doesn't get near enough credit for his offenses. especially his passing offense.
