And, I suspect that his listed height is generous. A 6'5" guy who mainly scores in and around the post is going to have a lot harder time in the pros.
I could see him making an NBA team as an energy guy off the bench, but I would be surprised if he is a 1st-round draft choice.
My take - enjoy him while he is at the U.
FWIW, Richard Coffey, one of the best rebounders in Gopher history, played 52 games in his entire NBA career. Murphy is a better scorer than Coffey, but Coffey to this day is the best pure rebounder the Gophers have had in the modern era.
