Of course, I agree with your assessment about teams that manage their use of the big guys down the stretch and the end of the season. But all that implies as that a team has to have the horse-power to begin with so that they can rest them and make the playoffs and not kill themselves to grab first place. For example, Celts Big 3 (really 4) may have been rested properly. Hopefully, they'll make the Finals, but Orlando has a lot to say about that one.
The tell-tale dynamic with LeBron was seeing him in the 2nd half just standing around on the perimeter watching the action. When he shot the 3-pointers, he went 0 for 4 attempts.
Theoretically, the 'wiseguys' sports-talkers said "he was probably trying to act as a decoy." To me he just looked like he was disinterested or depressed and clueless. Cleveland fans have been screwed. They just had no team around to support him. He failed to repeatedly charge at the basket himself. He opted to pass and dish off, but none of this teammates were effective offensively - not Jamison not anyone. Not enough decent shooters on that team or any that have a clue to crunch time and what to do in dire immediacy. Except lose badly!
