I disagree. I think being close to home can be a factor and will certainly give us one more feather in our cap. There might be totally valid reasons why he has eliminated Minny and Wiscy despite their proximity, but that doesn't preclude him from putting some weight behind distance.
Having your friends and family being within driving distance to come to several games per year or being able to run back home for a weekend, might be something looked at positively.
Also, him going to the east coast for prep school could give him some things to think about in regards to where he wants to spend the next 3-4 years of his life.
Ultimately, this move tells me we're looking good because he would rather keep Minny in the fold as a token local school, but has no reason to do that with us. So it's unlike say Harrison Barnes, who was only considering ISU because of distance, but in KW's case, ISU is a true player.
