Robert Williams is listed at 6'-8" on his ESPN profile. Yes, he plays a "big" 6'-8" but that is still 6" less than Moses Brown who is listed at 7'-2". I also agree with other comments that length is not the only important thing for an NBA center but come on, 7'-2" is way better than 6'-8".
I don't understand why OKC would give him up. They may well know a lot more about his limitations than any of us but he does not seem like the kind of asset a rebuilding, start from scratch team like OKC would give up.
I would guess that we are going to try to trade Thompson to free up even more money but I am not sure where we can send him. Maybe GSW? Don't see how the $$$ would work though. Is there a "Ideas to trade Thompson" thread?
I don't think they gave him up necessarily, they just wanted the 1st round pick more. And I think they probably wanted the 1st round pick more because I think they intend to dump Walker off on someone and believe they may need to include a 1st to do it (depending on the trade).
Thinking this through, if they are going to use the Celtics pick to dump Kemba on the Knicks (for example), then they really don't end up with anything from this trade. They would have been better off to just stretch Horford, keep Moses Brown, and move on (plus or minus some second round picks).
We'll see how this works out with Walker and what they end up doing with the pick but as it stands, they are going to end up paying Walker about $30M more than it would have cost to just cut and stretch Horford. Is it worth $30M to "upgrade" from Moses Brown to the 16th pick?
The only logical thing is that they must feel they can get something for Kemba Walker rather than just dumping him, and figured they couldn't get anything for Al Horford. If not, this trades nets them nothing.
