you just have to wait in see them in game. honestly it took me a half of ncaab to see purvis was no point guard but more of a defensive spot shooter type. He doesn't have many moves off the bounce or in triple threat, frankly i dont think ive seen him hit a heavy crossover in two years.
this isn't an indictment on rp as much as it is to coaching ; adams, larrier and enoch not taking a serious leap should draw more eyes to the staff on how they do with player development. One thing i'm optimistic about on that end is the hiring of coach killings, he did PD at the dleague level and developed many productive high d1 guys (cummings, decosey, dalton pepper etc).
