Oden for Calderon is an amazinly good deal for you. Calderon is probably going to be a top 3 fantasy PG next year. However, if you lose Oden you are going to have to pick up another big man. I would try to move Gerald Wallace or Durant.
Jump on that before the newbie who offered it withdraws. Calderon is going to have top 30 value this year, provided he stays injury-free. Best-case scenario for Oden is 12-15 pts, 10-12 rbs and 2-3 blcks (that's Tyson Chandler minus 6 blocks a week). That is when he's not getting MRIs.
