Well, there's obviously the advantage of more money the next recruiting season.
Keep in mind, though, that you only get that carryover if you fill all of your scholarships. If you take a walk-on then you don't get it. (If, however, you sign a JUCO and he doesn't show up, you still get the carryover.)
Or if you don't have any scholarships to fill at all, you carryover 100% of whatever you have (tourney $ or carrover from previous season).
