If Dallas was not willing to give more, we had to take the deal. Keeping Rondo would have been shooting ourselves in the foot. The only way he would have stayed was if we overpayed him.
Dallas has assumed a lot of risk with this deal. Rondo is not good enough at the moment for teams to offer rich packages, especially when he will be a FA at season's end.
It is very possible that Rondo does not perform well in Dallas and they let him walk to a team willing to pay him more at the end of the season. I look forward to the first time Popovich breaks out the hack-a-Rondo in the 3rd quarter.
When it isn't even clear that Rondo will make Dallas better, why would they also trade Parsons, one of their core players? Especially for Green who can bail due to a player option.
Lowe is correct. Once Rondo tore the ACL, we lost our chance to get much for him because it still isn't clear what his value is.
