Bosh didn't play notably poor defense this post season with the exception of his first game back from his strain.
His defense was pretty poor. The reason it might not have been "notable" was because he played against some pretty poor PFs in the Heat's run. He got a hobbled Amare, and then Steve Novak. Amare still shot 56% against him, including 62% in the final three games. Next was David West for one game (West outplayed him). Then on to KG and Brandon Bass, neither of whom is a dominant inside player.
Roy, you're usually very convincing, but not so much here.
By what standards was it poor?
Your criticism of Bosh's defense is summed up by this:
-Well, he played against a hobbled player in round 1. (He can't help whether his opponent is hobbled or not)
-He was outplayed for one game by David West. (You're talking about the game Bosh got injured in the middle of and only played 15 minutes in! Even if so, one game doesn't say much.)
-KG is not a dominant inside player. (KG was a top 7 player of this postseason. And I know you watched the games, so I don't see how you missed him establishing low post presence
frequently and doing work inside and outside all throughout the playoffs. Also, Bosh guarded KG immediately coming back from (probably prematurely considering the series score) an injury.)
