trobone, that's one theory, and there's merit to some of it - however - D I is a different beast, at least BCS D I is. Learning the ropes in a filling up/maybe gets full MWC with even more experienced coaches (to augment the really good cadre already there) is a really good idea. North Texas lets you recruit in the midwest too. Just my $.02
ETA: Making the NT by crushing a conference full of weak simmys isn't going to prepare you to compete in the Big 12...plus, in a fuller conference like the MWC you'll get more recruiting $$, which means better teams faster...
