DD's "success" was once, from fourth place, the team got on a eight day hot streak. DD "continuing" that would have been that happening again some day. DD was a poor basketball coach and should have been fired long ago. Only a Marshall fan would think making the second round of the tournament, once, something that literally most of the entire Division has done, is "successful".
But that is the past. DD is gone and the AD who hired him is gone. This is a token effort. The NCAA says we have to have a men's basketball team, and CS, cynically, knows that he can have just about anyone coaching any level of players, and go about .500, which is the goal and we will end up one or two games on either side of it. This is a built-for-football league and half of the teams make NO effort at basketball, some because they don't care, and some because they don't have the cash. It is easy to go .500.
And the same 2K or so old people that attend the games will still do so, and the student activity fees will roll in involuntarily, and this makes money on a cash basis.
That is the goal. That is the CS way.
