I checked this on the espn trade machine and I think this would work
Bass for Nick Collison, Perry Jones, Andre Roberson, future lotto protected 1rst
I think something like this works for both sides and this is why; Bass will only help us win games and get in the way of our younger players developing, which isn't something we need. But he can help some other team and he's an expiring. OKC has tons of young mediocre forwards like these guys that get very little playing time and they just drafted two more (Mitch McGary and Josh Heustis). These young kids have renewable contracts so they need not make too much money with us for too long either, but we get more youth to check out.
I think there are things on both sides of this trade to like.
I think at least we have to think this way. A contender trading some youth for a vet that can help.
Another similar thing I found would be
Pacers get Bass
Celts get Solomon Hill, C Copeland, Donald Slone, and picks
