He put him into the game in the late third and the C's went on a 11-0 run (part of the overall 15-1 run).
If he thought Bosh wasn't moving well on defense as the only big man then I understand why he didn't want him in the game.
Bosh went out and the Heat went on a 16-4 run and he stay with LBJ/Haslem as his 5/4 combo the rest of the game but the C's fought back and won.
Really good points. I think Spo is not up to the task. Not in the same universe as Doc, or Carlisle, or Pop, etc, but on the matter of Bosh being in or not towards the end of the game, I can't fault him in light of what you've noted above.
If they don't win the championship, Spo should be fired. They might not want to break up their 'Big 3' until they are given a year with a much better coach, which seems way smarter than trading Wade or Bosh AND keeping Spo, although if it were my team, I'd both fire Spo, and trade either Wade or Bosh, for say, Darren Williams. I think a top flight PG would be much better fit for that team, than say, Wade is. Wade is too much like James, only James is better.
