Dude you can't use the BS "his guys" argument. Prohm is a good recruiter, its proven he can get talent. So while guys like Monte, Naz, and Matt might have been Hoiberg recruits, they played just as much under Prohm as they did Hoiberg and I'd argue that all 3 of those wouldn't have seen the success they've had without Prohm. Matt didn't hit his stride until his work with Prohm and seemed to be a headcase under Hoiberg and Monte didn't get the greenlight for his patented pull up mid-range jumper until Hoiberg left.
And before you say, but but transfers. Yes Prohm missed on some transfers and it's probably not his strength, but I'd says he's been just as successful with the sit out 1 year transfers as Hoiberg. He's been pretty bad at getting the immediate eligible transfer, but I think his success with high school kids outweighs that.
