I'm posting a little before the draft because of a timing issue. I'll finish Mavs/Heat later. Here are my top 5 for each position:
PG: Kyrie Irving, Kemba Walker, Brandon Knight, Josh Selby, Nolan Smith.
SG: Jimmer Fredette, E'Twuan Moore, Jacob Pullen, Malcolm Lee, Alec Burks.
SF: Marcus Morris, Klay Thompson, Kawhi Leonard, Chris Singleton, Tobias Harris.
PF: Derrick Williams, Enes Kanter, Markieff Morris, Tristan Thompson, Jan Vesely.
C: Keith Benson, Josh Harrellson, Jonas Valanciunas, Mamadou Diarra, Donatus Motiejunas, Giorgio Shermandini
Edit: I had mistakenly Tristan Thompson down twice; this has been corrected to Klay Thompson.
