Im not sure that Park is above Randle and Exum. I think the top 5 in this draft all will be allstars at some point barring injuries. Wiggins, Parker, Randle, Exum and Smart
Outside of that five I think Andrew Harrison has the potential to be a dynamic scoring PG.
I also think Caulie-Stein is going to be alot better this season and develop into an above average starting nba center.
