When he arrived, Kelly did not seem to differentiate between interior OL and tackles. Last cycle, he decided he needed taller OTs. Not sure how this will evolve moving forward. While lots of folks here want us to morph into Bama, I don't see it. From what I have seen, Bama doesn't have a mobile QB or run a lot of empty backfield. We do. Kelly seems to be developing his own model, something between Bama and Oregon. Not sure that I have seen a comparable offense (Meyer?, Nebraska?) and not sure how this will evolve. Spring and fall should be interesting.
