If the question is 'straight up', i think that's a hard sell.
1) Green's the better player;
2) The Cs have more leverage for Green because he hasn't been pouting on the bench / begging for a trade, nor have the Cs committed to trading him by Thursday;
3) Green doesn't need to be paid $15mil next year. Us bloggers may not care, but i bet you Wyc does. Watching Green dunk sells tickets. Watching Asik rebound doesn't. $6mil ain't chump change.
