I understand the payroll difference, but the talent between the 2 rosters is similar. And, they had the #3 recruiting class in 2014 and the #5 recruiting class in 2024. The money is only keeping them in their position in college football.
A few differences that fall under two big headings:
1) Recruiting classes will be much less relevant going forward with the transfer portal. Coaches have blown it on recruiting classes over the years (Mack Brown could hold clinics on it during his time at Texas), but the transfer portal is much lower risk. A staff can bring in an experienced player that can play now, rather than have to project a 17 year old kid out 3 or 4 years. Where would you rather spend your money?
2) In 2014, the experience for a star player was not that much different at tOSU than it was at Georgia Tech or even Boise State. Players would pick their school on several factors, including how good a team was projected to be, playing time available, and the coach. Going forward, money is #1, #2 and #3. Everything else is secondary or tertiary. The schools that have the money to spend will dominate with the top talent, and with the bench players. Top schools will be able to pay preferred walkons more than they would make starting at other schools.
Unless there is revenue sharing or a salary cap, the difference between the top schools and even the schools just outside the top is going to be massive.
This problem will be much worse for football because the rosters are so big and so many players contribute every game.
