If you like wonky football Xs & Os and the evolution of an offense, read this Grantland piece on Urban Meyer's incorporation of Oregon schemes into his offense. Due to Addazio's ties to Meyer's power/spread/option work at Florida and Ryan Day's ties to the Chip Kelly/Oregon tempo/spread, there are elements of both styles in BC's offense. However, the Addazio/Day hybrid has been very different from both (so far).
As Grantland pointed out, Meyer still uses power, but also added much more zone blocking schemes and attacks the defense outside the tackles. Since leaving Florida and partnering with Day, Addazio has doubled down on power. We between the tackles all the time and even when we throw in a jet sweep to Alston, it still has power elements. BC also runs more than Oregon or Ohio State. The only programs that run more than BC tend to be teams that run variants of the triple option.
But how much of what BC does is by design and how much is necessity? Addazio didn't inherit a roster like Meyer's or spend the past decade recruiting speedsters like Oregon. Other than the power football, the only hallmark of Addazio's first two years is his ability to adapt his offense to the talent available. He's not stubbornly trying to shove a square peg into a round hole.
I expect BC's offense to continue to evolve. Will they follow Meyer's path or will they incorporate Kelly in different ways? It will be interesting to see. But at least Addazio and Day's peers and role models are showing that you have to keep adapting and changing. Hopefully their adaptations lead BC to a championship game like it did for Urban Meyer.
