why would each team do the trade?
Cavs: they move Mobley to a center defensive role, they get PJ a perfect piece to their roster, they get a deep bench efficient role player and a FRP.
Hornets: they get a good volume shooter and 3 SRP for a player they don't wanna pay.
Mavs: they get a starter center.
(the SRP from the spurs are from the Grant Williams trade)
