Yeah, I'm assuming that McMillan thinks that moving Lance onto TT would mean too many offensive rebounds
If anything, the reason why Bron would leave the Cavs is because of games like this. This is game 7 of the FIRST ROUND, and Bron has to play all 48 mins at his age.
At 33, you should be trying to think of ways that you can preserve your body for the long haul, not playing the entire game. I don't care who you are, it takes a toll.
