They're tanking, I'm bored so decided to help them.
OKC Send; Perkins, Lamb, Perry Jones, a first round pick.
OKC Receive; Marcin Gortat, P.J Tucker.
Phoenix Send; Marcin Gortat, P.J Tucker.
Phoenix Receive; Perkins, Lamb, Perry Jones, first round pick.
OKC get a proper big man, finally! Helping with their playoff run. They ditch Perkins and his awful contract. Phoenix are tanking anyway, they get a couple of good young talents and a first round pick to help with the rebuilding.
Yeah, idea 1 might work though OKC FO seem to love Perkins beyond basketball reasons, idea 2 isn't happening, if they really want to trade Asik they'd look for more reasonable fits than Gortat. who just brings back the same problem while being generally less of a player than Asik anyway.
For Asik, the 3 trade I think could work and probably either Millsap / Thad Young / Jason Thompson , though the timing is probably not now anyway, they really should see if this group work, if it does it's probably their best theoretical ceiling group. and there are at least some reason to think it can work. (including the part that most teams that win it all managed to make some weird fits work.)
