According to J.A. Adande (who reported this on ESPN.com's NBA Today podcast; go to around 17:50), Cavs owner Dan Gilbert has been trying to consult with LeBron on the various firings and (potential) hirings going on this off-season, and LeBron has demurred. Adande says that LeBron doesn't want to give an opinion because he doesn't want "blood on his hands" if those moves don't work out. I can see the logic in that.
I can also read between the lines and see a LeBron who is avoiding giving any signals that he's coming back, who's trying to avoid creating any more ties between him and the organization.
Now, maybe he resigns with the Cavs anyway. And maybe it is just that he doesn't want to share any responsibility for a new GM/coach's potential failure. But it sure does seem like he's trying to keep the slate clean with respect to his pending free agency. Not a huge deal, but I found it interesting.
(In other news, around 25:00 or so -- maybe a bit before -- Adande espouses the view that Bosh is the first domino this summer; where he goes will determine how the rest of the dominoes fall.)
