One of the few trades that I can see happening without the Cs giving up a rookie contract player or a 1st round pick.
Logic:
MIL won't take Bass or Terry for Delambert straight up, I'd suspect. But Gooden is absolute deadweight on the Bucks... he's less tradable than Bass on almost precisely the same contract. Presumably they'd happily take Bass in exchange for Gooden straight-up -- a hard situation to find across the NBA.
Milwaukee struggles to be relevant (and attract FAs) in a small NBA market. Yet they're still above .500 and looking to compete, in large part to increase their chances of convincing Jennings (OR Ellis, to a lesser extent) to stay after this season. Terry acts as the primary back-up this year, a valuable bench guy for the next couple of years, and brings championship pedigree to a young locker room.
For the Cs, my POV should be obvious from this trade. I don't see Terry's impact being enough to prohibit moving him for Delambert, who despite likely having been out of shape, has picked up right where he left off in years past under new coach Jim Boylan -- productive and disruptive.
The wild card is Gooden. Strange the way when he played for MIL last year, he played well, and yet now he never plays. If that's because of the depth of young guys they have at the 4 (Sanders, Ilyasova, The Fresh Prince), then I think he's a wash or even an upgrade from Bass. If not, well, not pretty...
To me, it's worth that risk for a significant upgrade at the 5, and 2 years less of either Bass or Terry, depending on how you look at it.
