Let's compare apples to apples. The data follow college football teams 2014-2018, where we are 47-19 (71.2). Conference win percent 66.7%. (30 wins) .467 draft choices per win, 2.14 wins per draft choice.
For the same years, conference wins-draft choices-draft choices per win-wins per draft choice:
Penn St.27-21-.778-1.29
Iowa 27-15- .556-1.80
LSU 25-27-1.08-0.93
Florida 25-33-1.32-0.76
aggy-20-20-1.00-1.00
UCLA 20-22-1.1-0.91
Michigan 29-24-.828-1.21
Washington 30-24-.80-1.25
I got tired here but there are many more. Looks like, from recruiting rankings, TCU recruits way below many teams but still develops an amazing amount of NFL players who should have no chance based in HS, and with less NFL talent than many teams, wins a lot more games (if aggy was a 2 wins/draft, they would have won 20 more games, if TCU had as many NFL draft choices as aggy, they would have won 12-13 more games) Yes, I know there is not a direct correlation, but it obvious how much better TCU does with talent than many of the "name" schools.
