While I would love it if one of the better players fell to the C's pick, here's my non biased Big board.
1) Karl-Anthony Towns - More Potential, could be what Andrew Bynum wasn't
2) Jahlil Okafor - Could be an all star, lower floor than Towns
3) D'Angelo Russell - Going to be a good scorer in the league, next Damien Lil (Take that to the bank)
4) Emmanuel Mudiay - Seemingly great feel for the game, needs to work on jumper but otherwise exciting player
5) Justise Winslow - Even though Johnson is bigger than Winslow, Winslow has a better feel for the game NOW, Excellent defender, needs to work on J
6) Stanley Johnson - Another high potential wing player, Body is already there, game isnt yet
7) Kristaps Porzingis - The next Dirk? ( Kelly O? LOL ) But I'm very iffy on taking foreign players with top ten picks. High Potential, needs to work on strength

WCS - The next Tyson Chandler (possibly a better on ball defender)
9) Mario Henzonja - another foreign player, very cocky but has all the tools to be an elite player in this league. High Risk = High Reward
10) Myles Turner - Didn't have the best season but he wasnt utilized well at Texas. VERY high potential in shooting and shot blocking but major chance at bust
11) Kelly Oubre - Reminds me of James Young, good shooter, suspect on defense. Good overall player, could be great if he gets his mind on track
12) Jakob Poeltl - BIG kid. Good defensive center. Lower floor but not the highest ceiling. Solid C in the league one day
13) Frank Kaminsky - Reminds me of a more aggressively Kelly O. Stayed 4 years at school so he is already around 22/23 years old.
14) Bobby Portis - More in shape Sully
15) Devin Booker - Going to be the league's next knock down shooter. Maybe Danny Green or maybe even Klay Thompson
16) Tyus Jones - I didn't have him in my top 20 before but after his clutch play bringing Duke the ship I had to
17) Trey Lyles - Very Lanky, pretty Raw in my opinion. Could be a good player in this league if utilized correctly
18) Montrezl Harrell - All heart and grind. Would love to see him in a C's jersey as our PF. Needs to work on offense
19) Jerian Grant - Back up PG on a good team or starting on a rebuilding squad
20) Sam Dekker - Tournament impressed me but I don't believe he could keep those numbers or defense. Excellent high for a SF though.
