I would much rather have Joe Smith, but if we waited to see if Danny passed on Moore and Smith never got bought out, or worse yet signed with another contender, everyone would be on Danny for passing up Moore.
While Moore doesn't excite me too much, I can't think of too many free agent centers during the off season that would've excited me more. Only one that comes to mind is Chris Andersen, and we don't know if the Celtics ever really stood a chance to sign him.
I assume the Celtics can still sign Smith if he eventually is bought out, and could then cut Moore. Although I doubt that would be worth the risk of ticking off an agent like Mark Bartelstein. But also, the Celtics have 2 open roster spots, so while it would be best to get a big and a point guard, or a big and a wing, if no point or wing comes along that could help us, it wouldn't hurt to have both Moore and Smith on the roster. And while it would show that Danny really missed the boat with his 1st round pick, he can still always waive Giddens as well.
