After this mock trade:

Cavs will finally make some change. The twin-towers lineup have unresolvable flaws. P.J. will be a modernized 4 to pair with Mobley. Fox will be a younger replacement for Harden with better defence. BTW, if Bron decides to take a vet, Fox - Spida - Bron - P.J. - Mobley would be a truly contender in the playoffs.

Mavs will get Harden to pair with Kyle. This will be their second chance to prove everyone was wrong. Kyle + Harden + Risacher + Flagg + Lively would make a big push for the next coming season. Morez & Keldon can come from the bench with energy and efficiency.

Spurs will get Allen to pair with Wemby. They will have chance to play Wemby at 4 on offense and defence still at 5. Klay & Strus can space the floor so well and their expiring contracts will help them have huge salary flexible to extend Castle & Harper.
