As much as I like Harkless, I would prefer the C's to resign Jeff Green and see how he pans out as PP's backup. If Danny decides to go in another direction, then Moe would be a great pick.
We need to pick up AT LEAST one big in the first round, so I'd say Nicholson(who I really like; a tandem of he and 3J would be sweet in the future) or Melo(reluctantly) would be ideal big men to pick.
Will Barton is a guy I could see become a super 6th man. A 3-guard weave between he, RR, and AB would be sick. But, if we take Harkless and a big in the first round, I belive our second round pick should be used on Tu Holloway. I know he's short, but the guy can ball big time.
Tony Wroten Jr. may have incredible atheticism, but I'm not sure his IQ will impress Doc. I see him as another Gerald Green, personally.
