Here's another consideration- because Altman was able to pull off a trade that is being pretty globally as successful, this act may have a positive effect on LBJ.
He liked Griff, but griff routinely blew through assets to make any deal, and failed to do anything last summer and was failing this year when he was let go.
Having a GM that makes good deals will only be looked at as LBJ as a plus, and resolving this situation in a positive manner can have long term effects on the teams relationship with LBJ.
In short, the Cavs appear to have a pretty damn good GM, which helps the perception if the forint office and ownership.
Also, good job Dan Gilbert. apparently GMs are available out there.
