The goal is to have the advantage in all 3 of those facets you mentioned (and add out-talent to that) in order to be an elite team. That's the end goal. That's where the Bama/LSU/Clemson/OU/tOSU*'s are today.
It's not that we have to have those things to beat teams like Duke/FIU/GT, it's that...
This. 1000x, this. This all boils down to having the right culture, and the players buying into it. That's why Clemson can reload at spots like OL with guys that aren't the highest ranked players, and still operate at a high level.
