Saban, Miles, and Stoops are in a league of their own. Spurrier would be too if it didn't take so long to get SCar out of the basement.
I'd almost leave Miles out of being mentioned. 3-14 before LSU, at a marginal Okie State program, then 37-19 at a LSU team that Saban built up.
Saban, before Alabama, was 22-23. Of that, I believe he was 18-9 at LSU, making him 4-14 back with MSU/Toledo/Kent State. But 18-9 and 28-12 at LSU/Alabama, where both were not very good when he arrived (though, admittedly, both have great recruiting bases and having traditional prestige).
Oklahoma has the same prestige and recruiting base, but I remember them going through a rough decade or 2 pre-Stoops.
Kind of odd to see Urban not have nearly as many top 25 games, but he's got a good record, and besides OSUn, he helped build the teams up (Florida's coming off of Ron MF'ing Zook).
