Detailed breakdown of Cauley-Stein (by Fran Fraschilla)

[Sixth Man]

This is a nice breakdown.  As FF says, role players can be very good.  WCS could be a Kyle Korver of the defensive pogo stick role.

I agree, but I also suspect that he may be even better than that, as he is something that Korver isn't - a superb athlete, and a seven-foot one, at that.  He is the one player I really want from this draft, but it will take an established player and multiple picks to acquire him.

I feel Fraschilla's assessment is spot on.

The C's should package a player or two, plus their pick and move up, and see if they can't steal him from a team that already has a front line center. Or possibly throw in another 1st rounder from 2016.

I'm not sure the Celtics will be in contention to acquire a solid center in the 2015 free agency, seems like many of the big guy's are staying home.

I don't think it's spot on from the offensive side. WCS has no offensive game other than at the rim. His TS% is likely to suffer a bit in the pros and having more space to operate in isn't his issue offensively. OTOH, he is playing close enough to the hole to get lobs in a PnR and runs the floor well enough to not be a complete zero like some D big men.

Defensively, he looks to be elite and should be outstanding against the PnR with his ability to recover.  Blocks are very over-rated, but there are legitimate questions about his rebounding that appear to be unanswerable due to the way he was utilized defensively. There's a split on WCS and I'm not sure about him either. We need a rim protector, but we need more offense as well. Not sure Turner is not a better choice if his legs are OK given the lesser cost to move up.

Secondly, we have assets to trade up with someone like SAC at 6 who's dying for a PF and/or SG, our picks this year are worth more than theirs (according to Tankathon's power rating), and they don't need a center.

It would be nice to get Okafor or Townes, but we're most likely not going to. Many teams get along fine without major scoring from their center. When that center plays solid D, protects the rim, and rebounds. Besides we have Zeller who scores fairly well also getting minutes.
You're simply not going to get a center with everything you want drafting between 10 and 15. We can find scoring elsewhere.
