I guess if there are, what, 8 teams with big cap space and the room to sign 11 or 12 huge contracts...?
We know of 8 those contracts are going to James, Wade, Bosh, Stoudemire, Johnson, Boozer, Lee, and Gay. If you assume Pierce and Nowitzki stay put, that still leaves lots of money on the table for someone to overpay (and over too many years) Salmons and Jefferson.
There's just a ton of demand out there. Two-years worth, basically. And next summer is a complete unknown. No wonder everybody who can opt out, is. (Except for Yao. And even that's sort of surprising. Missing one leg or not, wouldn't the Knicks love to overpay him when they miss out on everyone else?)
