THunder have no young players the Sixers would have any interest in. The deal would only work for Sixers if they get a big expiring and a lot of picks.
Perkins wouldn't expire until next year but I think they would be fine with that considering they want to tear it all down and just suck. Perkins will certainly help them suck.
I'm sure GM's are interested in Jackson/Lamb/PJ. All three of those have ability but uncertain futures. Jackson actually will probably be a starting PG in the league.
