When people say that basketball is dead in the south its usually from a place of ignorance. They either just don't really like basketball generally because they may be more of a baseball fan or they are just spitting out something they heard some talking head say.
I think the folks at McNeese would beg to differ or just across the south in the SEC and parts of the Big 12. You are seeing major growth and the SEC has become the premier conference in the country although I hate to say that (ACC fan).
Many programs are dumping large amounts into their programs and they are seeing record attendance numbers. We, as a city, may be a bit of an outlier though as we have seemed to take over a baseball culture more here. It's sad but it may be true but the sport is not dead on a collegiate level at all in the south. It appears to just be so here.
