From my understanding, the current programs (stadium, practice facilities, training facilities) in place could get "fast-forwarded" with an influx of cash. On top of this, I would imagine the dorms/appartments that the players reside in are outdated and, frankly, dumps at this point. It's hard to recruit a kid and his family when the place they'll be living isn't up to standards compared to other schools.
Also, I think Franklin would like an even bigger budget for his coaching staff/salaries - we've made some progress there, but it's essential to keep guys like Seider, Yurcich, Stubbs, Pry, Dex for longer periods of time. And even when these guys do leave for promotions, we need to be able to hit on top candidates to replace them. BOB going to Bama, and Elijah Robinson staying at A&M are top of mind examples. Also, remember when OSU had Urban, Day, and Kevin Wilson all running the offense? Or Joe Brady + Ensminger at LSU in 2019?
