Both Briles & Heupel are branches from the Leach tree; Leach went & found Art down in TX HS coaching because he saw how he revolutionized the Veer & Shoot Offense at Stephenville & brought him in at TTech. Heupel played for Leach at Okla for a year & got his start in coaching under Mangino, Chuck Long & Kevin Wilson.
He & Lincoln Riley basically run the same system with different variations & certain aspects as far as personnel groupings & spacing; Heupel has more of a traditional AR passing offense with the wide spilts & combined it with the uptempo Spread rushing attack, while Riley doesn’t usually split the wideouts that far towards the Boundary & has a bit more of advanced rushing attack. But both systems are highly potent & give DC’s nightmares because it puts so much pressure on your secondary to have to be **** near perfect in coverage to slow it down.
Briles’s system is more so predicated on having a Mobile QB who can work the Mesh points & utilize a lot of QB Option runs out of the Pistol to keep the Defense off balance hence why he & Kendal pretty much always produce great rushing offenses everywhere they go. Art’s passing concepts are a lot better than Kendal’s though & I think his schooling under Leach is what helped Art in that aspect, while Kendal is still developing that part of his play design/play calling repertoire & his stint under Kiffin at FAU has helped improved him some in that area.
There are some other coaches who run the Briles style Veer & Shoot, mainly Sean Lewis & Andrew Sowder at Kent ST (both are Babers disciples), Mike Bolesch at North Texas is another one, Sterlin Gilbert was too for awhile as another Babers underling. There’s a few more, but the reason why it’s not as prevalent is because it’s a system that has an insane amount of volume in the run game & when at optimum level it’s acts as sort of a stress tester for your OL & QB; It also is mainly a system that’s born from Texas HS Football, so it’s kind of niche scheme that only a few really know how to run it properly.
It’s not as malleable as the Air Raid.
