The NBA released it’s salary cap figures for 2010-11, and surprisingly it came in at $58 million, about $2 million higher than expected. That gives everyone a little more to play with, but still means LeBron would leave a significant amount of money on the table if he decides to leave Cleveland.
Amateur math, guessing a bit on max number. Full max with Cavs for LeBron: 6 years, $128 million. Elsewhere: 5 years, $99 million
