I was at the two Belleville games, and one thing that really impressed me about Reinbacher was never out of breath after a shift (I watched how he was breathing after a shift, stuff you don't see on TV), although I didn't look after every shift. On Saturday, he even had his mouth closed after a shift. That tells me his fitness is excellent.
Also, I think Baroon gets way too much criticism. He was on in all situations, that tells me Houle trusts him
One last thing, Kelly Buchburger has a very good relationship with the players, after every shift, to every defensemen, he gives them a pat on the back. If that player had a good shift, they might get two or even three. He also fist bumped every kid as he went to the bench (the coaches walked around the arena, and did not enter the bench from the ice).
