I think there's a lot of talk about Rondo because he's the only 'exciting' name on the roster at the moment, but realistically Danny's asking price is probably too high for anybody to make a strong offer.
His asking price is reasonable, people just think he's going to give away Rondo for whatever he can get.
I never said Danny's asking price was or was not reasonable.
My point is just that the offers for Rondo are going to be lower than Danny is likely to accept because Rondo is still not far off from his injury. I do think that Danny likely values Rondo higher than most GMs in the league probably do, just because Rondo's a unique talent and the Celtics know he likes being in Boston and that he can succeed here.
As you've said, there's no reason for Danny to have a sense of urgency to trade Rondo now, if he's going to trade him at all. So he's going to have to receive a really strong trade offer to get him interested.
I think you do have to factor in position when you're talking about a player's worth, though. Rondo is definitely a very accomplished player, and he's better than most other guys at his position. But the overall talent level at his position is strong, so not many teams have acquiring a point guard as a major priority.
