Trade gives us a lot of flexibility (14 mil trade exception) being under the cap also gives us few draft picks to work with for next year. Metta's contract is over after next year (team option).
We are no longer forced to use MLE on Lin can sign and trade him if a good offer presents itself and go after dragic or nash. We can use the trade exception to go after Andre Igudola or if healthy go after Jeff Green or even better put a big offer to Batum early in free agency (or talk with portanld for a trade). Easily fill the bench with good quality players (KG, JR, Novak, Lin/Dragic, Fields, Geral Wallace).
We could field a good team without going so top heavy.
