I disagree I think by his junior and definitely senior year he will be very good and starter material. He is a good program SU player being developed for his later years. He will be a great compliment next to a stud one and doner. That may well need to be in his junior year when SU gets picked over by the NBA and both Battle and MR leave.
FH's role will slowly increase. Right now JB gets riled up when he acts outside of the role his is supposed to be taking on. As years go on, JB will ask for more out of FH.
As of right now, FH looks to be a key player in the '17-'18 season. FH, 7'2", Moyer, and hopefully Lydon with some one and done scoring guard look like the makings of a good team.
