He is technically the 4th big man and has now been in the system for his 3rd year and cycle. If we played Jake Dadika and Joey Downes in blowouts in wins or losses, I can see Nathan finding minutes in more than a handful of games.
He has fairly good fundamentals but just isn't a true B1G caliber rotation player, game in and game out. I do think by this time next year, Nathan would be capable of being a 8 to 15 minute a game player and if he was at Columbia, Colgate, Bucknell, Boston University type of program, he would be a 10 and 7 type of player in his junior and senior seasons. He is a RS Sophomore which buys him the next 3 years.
