I think the the question with John will be his mobility on both ends of the court. He can shoot and pass, but if his mobility wasn't a question, he would have been a top 50 recruit (or better) instead of a top 100 recruit.
In September, I talked to someone who knows Hugley's abilities very well and he had significant concerns about his mobility then, even saying that he didn't think he was yet ACC ready from that standpoint. However, I does look like he's made some strides since then. I can't say how much though.
In short, until I get better evidence, I expect Big John to play a role similar in size and minutes to Eric Hamilton. If mobility is an issue, foul trouble will likely follow. I do hope John improves our rebounding, because we certainly need it. Even if he just clears out space, perhaps he will let some rebounds fall into the hands of other Panthers. But Eric Hamilton type numbers in terms points and rebounding are my expectation.
Hopefully, we will get much more than this from him of course.
