SEC is dominant in Smith. Conference prestige: A. Conference RPI hasn't been below .6000 for ages (.6288 in just-completed season, which was solid but unexceptional). A SEC team has either won or been defeated in the National Championship 11 of the past 12 seasons, with the title game being an all-SEC affair two times. Alabama, Georgia and Kentucky are all particularly ferocious. Everybody else pretty strong except for South Carolina and my Vanderbilt team, which are both trying to rebuild.
The Big 12 is actually the weak sister right now in Smith, sporting a B- prestige.
