His best friend from high school was there, and from what I've read that played a big role. He was top 140 composite, I believe, and had a lot of interest but only a few of the bigger named offers. He was short, and that scared people off, I think he will be first-team in that league no doubt, but I was surprised that he ended up there when I first heard the news as well.
Thanks for the answer. Are you of @CyTwins opinion that he is as good as Jackson? I find it hard to believe, but Twins thinks Custer would have kept ISU from recruiting PG.
