As we saw from A&M, it takes much more than just buying a roster.
First, you need a head coach who prioritizes a mental/personality/cultural evaluation for players along with the physical evaluation. You need a head coach who's willing to say no to a 5 star that doesn't fit. Without this, you end up with the dumpster fire that was A&Ms locker room.
Second, you need a coaching staff with elite Xs and Os. Whether that's head coach or coordinators (i.e. Joe Brady for offense, Kirby Smart on defense, etc). Seems obvious, but without elite Xs and Os, it doesn't matter who's on your roster.
Then, third, you need the players to execute the Xs and Os at an elite level.
Seems like we are at a place where we finally have all 3 both on offense and defense (hence, back to back top 4 finishes).
If Tech jumps straight to buying a roster, they still ain't gonna do shit without the right head coach and coaching staff in place. They'll be more A&M rather than Texas.
