I don't see the Lakers taking on any deal that isn't expiring. They have only $9.7 million on the books next season (Nash), and if Kobe agrees to sign a cap friendly deal, could have room for two max FAs.
They should trade Nash to Toronto for expiring deals, either at the deadline or next summer, and they will have all kinds of cap room to reload (assuming that superstars like LeBron, Melo, Wade and Bosh want to move).
