MSSU is a good comparison. It's in a very good D2 league, but the school is known more for basketball. Recently updated football facilities that look pretty great. They have turned over coaching a number of times over the past several years and probably will again next year. Major investments in facilities, coaching, and a ton of marketing and still they went winless this year.
One difference is that I would consider Joplin more of a football town, where Springfield is more of a basketball town. MSSU has some very good high school programs nearby and interest in football is high here. Webb City is maybe 5 miles from MSSU, Carthage and CJ, maybe 10. Joplin HS football might be rebounding as well. So you would think they have a favorable environment in which to build a program. It could be that PSU is so close and draws too much of the local talent and interest for MSSU to gain traction? I have no idea. MSSU baffles me. Ton a potential and they seem to be trying but going nowhere. Just like MSU. Overall I think both of these institutions are doing great things - just not on the football field.
