This is actually a smart trade the works financially for both teams. I'd be happy with this. I'm not sure MIL would do it, but they're only playing Dalembert and Daniels about 18mpg. They could plug Bass in as a backup and see what they get out of Melo.
Dalembert would immediately become our best rebounder. KG would be able to spend some time at PF, while Dalembert filled in at C. Green would have to play some more minutes at PF, which I know isn't his strength, but it's a better option than signing Kenyon Martin to backup Bass.
If Ainge did this, he could turn his attention to bringing in a low-cost backup PG.
Good idea.
