I have seen it first hand. When I was a manager at SEMO, I was there for the last 2 in the MIAA, and the first 2 in the OVC.
We made the elite eight in D2 my first year there. Lost in OT to KY Wesleyan who won the next 2 by 25.
Our game was really for the D2 championship. Everyone there knew it.
I digress. We made the trip to Maryville, and our head coach used to always say "Maryville isn't the end of the Earth, but you can see the end of the Earth from there."
The difference was we got the same level of player or a little less, we got to go have our butts handed to us by the Nick Van Exel led Cincinnatti Bearcats, and the Corliss Williamson led Arkansas Razorbacks for 25 to 30 thousand a game.
Also got our butts kicked by Popeye Jones and the Murray State Racers.
I got to see some great players, but staying D2 coach Shumate could have lasted another 15 years there and retired.
