I get what you are saying, and I know similar things were said about Willis the first time he transferred here. I agree about the home town bias, but I also think (and I will claim myself) that being high on Kerwin is linked to our current inadequacies at guard. We need a guard who can shoot and we do have evidence that Kerwin can shoot. Many of us also live in mind frame that blue blood bench warmers are starters at lower level places like the U. Perhaps true and perhaps not, but it is believed.
Kerwin is probably not THE answer, but I think he can be part of the answer and is likely as good as, if not better, than our current shooting guard options.
If I'm the staff and he fits in the locker room, I offer him if he comes available.
