Guys were running through walls, whether or not Blatt is responsible he certainly didn't prevent it from happening.

Blatt lets LeBron run the show on the floor the same way any other coach dos but they do have a well-defined system and they did make quite a few adjustments as the playoffs progressed.

I'm not really seeing this as "up to Blatt." I don't think there is any doubt he would like to return, but there is some doubt as to whether or not he will. I guess a major factor is what potential candidates emerge.

As you'd already guess, I don't think he should be Rick Carlisle'd, but if he does I am sure he will land on his feet, and the Cavs will, too.
