I agree 100%. He seems, for lack of a better word, just overjoyed to be out there. I love how the coaches are handling him; just letting him run free like a wild horse, not over-coaching him. It would be very easy to over-coach a guy like Burns, but he's far better just being allowed to do his own thing. If a team wants to slow him down, it's like they have to focus in entirely on him, because he doesn't play a system.
Also, I wouldn't underestimate the effect Burns (and Hertl) are having on Joe. I like having those two play with Joe and Couture playing with Patty, just because I feel like it sort of reminds them how much fun hockey is and how lucky they are to be doing what they do, and also just dials up the enthusiasm. It's a really good mix of chemicals right now.
