It was the first game after a long break. You lose a lot of conditioning. Remember the bye weeks some years ago? That was a one week break, and they still lost conditioning.Chiarot shouldn't be on the ice in OT. He also isn't doing just fine, he makes plenty of mistakes.
Todd should still know that Chiarot doesn't have the skill set to do well in 3 on 3. Gus at least makes sense, cause he does have some offensive skill even if he pooched it yesterday.
