I'm pretty sure that if Gilbert traded Lebron, since he is basically the acting GM, his head would end up on a stake outside of the Q. Also, there's no way Chauncey Billups or any other GM comes to Cleveland knowing that they are trading Lebron. In the NBA it's much more difficult to make trades than MLB, so teams can't always just wipe the slate clean in the offseason. What Griffin did with this roster and the salary cap was very impressive and will be tough to beat. Even if the roster stayed as-is, we are still getting to the ECF versus Boston next year and i still like our chances as long as #23 is in wine and gold.
On a side note, if Lebron does leave as a free agent down the road, Dan Gilbert would forever be known as the first owner to lose the best player in the league to free agency....TWICE!!
