I've talked to quite a few people that went to school with Royce that said Fred deserved a Nobel prize for getting him through Iowa State for two years.Let's not get too enamored of the guy just because he looks like the next iteration of the patented Hoiberg Rehabilitation Project. He's got good numbers but there's no indication that he's got more upside than already shown. As for the personality issues, everybody's f-ed up in their own unique way, just because Royce's and DeAndre's issues were amenable to the Hoiberg treatment doesn't mean this guy's would be.
In the end, Keep calm and trust Fred.
