I'll float another idea. What if sources have it half-right and Dallas and Boston are talking trade, but it's actually in the context of Charlotte sending Lance Stephenson to the Mavs but not wanting Wright, so he gets re-routed to Boston and the Celtics give up Bass?
This would make a lot more sense considering Wright has never averaged more than 9 points a game or 4 rebounds a game. He is 18 months younger than Rondo, so he has been in the league for 7 years. He is no developing youngster.
If you think Jeff Green is what he is at this point, then Wright is there as well. I know he is long and can jump, but big deal. He is still another way undersized center and just further clogs up the PF spot. He isn't known as a great def player either. He shoots a high % because of dunking a lot, similar to T. Chandler.
So we get a center less skilled than Zellar (Wright) + a 1st round pick in the mid 20's or worse from Dallas depending on how much rondo would help them (probably a lot), yeah not a deal I am super excited about if I am DA.
