I hear what you're saying, Poison, but I think the offensive leader thing is overrated. Not turning the ball over and getting stops is first; I don't think anyone on this squad qualifies as a go-to scorer, the kind of player that you force feed shots when things are going wrong.
Both Kennedy and Horne may have improved, slightly, but they were on the court for Marquette and couldn't get a damned thing going. Neither is that great at creating their own shot. And one of the big problems was turnovers, check out the game play-by-play:

Plus, if there is a player like that who would be the, ah, "slumpbuster", it will be Mason, at the outset; both because of his experience and history and the fact that really, he's one of the better players at getting their own shot off.
