I just looked at the first year and this is why I argue it's more than talent all the time and that as crazy as it seems, Saban is underappreciated.
Look at the guys who went to Ohio State, Alabama, Georgia, Clemson.....(the powers that be) and how they panned out vs. how many busts there are among the players that went somewhere else.
This sheet reflects the current status (as best as I could determine) on the top ranked 250 players by Rivals and 247 by recruiting years. You should be most interested in years 2016 - 2021.
