but not all gap scheme teams have the OL to pull off a power heavy scheme. when a team has the horses to run power plays, they tend to run them a lot more than a typical gap team with an average OL. the old jim harbaugh 49ers and the early rex ryan jets had the horses to run power schemes and they ran a hell of a lot of them, as opposed to, say, the early cam cameron ravens, when yanda was still bouncing between RT and LG and hadnt really began flourishing yet, and we had just moved on from jason brown and matt birk was struggling with injuries for a few years, we ran a lot of lead plays with a FB, but up front we stuck with a more basic gap concept.
so my original statement still stands... power emphasizes pulls and leads more. sure, both gap concepts, but if you have the talent to run traps leads and pulls at a high and successful rate, then you likely will, because it creates a pretty successful running game compared to a vanilla gap playbook.
