I pretty much agree with everything MMT said. Mike Brown did a bad job against the Celtics, it's really that simple. The rotations Brown used matched up poorly with the Celtics had he gone with a lineup that featured Verajao guarding KG more (KG did nothing when he was on him) and smartened up and let Jamison chase Allen around and continued to let LeBron completely shut Pierce down and just let Rondo do whatever because even on his best day he's not beating you by his self the Cavs would've a great chance of winning.
One thing you did get wrong MMT is Rodman and Kukoc weren't there for the Phoneix series, Horace Grant was there who was still a very good PF and an all-star.
It always seemed to me that people were acting as if LeBron owed the Cavs something when he never did, and you summed it up nicely MMT. No matter who drafted LeBron he would've been just as loved by that city and he would've made that team just as much money. He doesn't owe the fans of the Cavs anything or the organization anything he just owes to the fans of the NBA to play his hardest, and that's pretty much it. It's funny how players are supposed to be loyal but when teams cut a player who's been there for 10 years because they don't want to pay him it's understood as a business move. Seems like loyalty in sports is a 1 way street, the players have to be loyal while teams should only do what's best for their team.
