Yea, I can understand. The front office when Lebron was drafted was pretty terrible. When Gilbert bought the team and changed management it took them a year or two (wasted years) to flip liablities into assets to be able to compete.
However, his unwillingness to coax other players to come to Cleveland in the off season combined with him not signing a third long term deal really compromised what the Cavs could bring in. I think they did a pretty darn good job, all things considered, puting together that 65 win team that got beat by the Cs when Lebron melted. They were better than history will remember them for.
You are right that his guarantee to bring a Championship to Cleveland added fuel to the fire, as well.
I am too excited for the Cavs future to be worried about him anymore, though.
