Wooden DIII is the only choice for DIII.
the DIII level has turned into quite a ghost town in all worlds. Wooden has quite a few full conferences and tons of rivalries all over. Plus it has wronoj's Dynasty List. Check the forum. a killer ranking of all DIII teams. . . . great conferences are the Midwest, Michigan, NAC, Minnesota, and Litte East
as far as DII, i know that Rupp DII had a big influx of coaches a year back (or so). dont know if its still "hoppin" or not though.
DI is competitive everywhere.
