For me (and someone that hasn't been above C- prestige in DI), it's simply a matter of what challenge you'd like. DIII is the 'level' playground, with higher turnover, more 'diamonds in the rough', and has fewer at large NT bids. DII has the most at large bids, the risk of the serious big boys dropping in on your recruits, and the challenge of *typically* better coaches on the lower half. Low DI is not for the quick fix or easily angered folks, you have to work your way up, have a plan, and stick to it. If that means stay in the Big Sky, or move up to the Mountain West in 5 seasons, know what your goals are to keep on track. And DI is the one place that you simply have to say, "I can't make the final four with this team, no matter what I do." (Yes, it's possible, but you can't go in thinking you're the special one)
