In live action, it looked painful. I thought he'd get a penalty, but was surprised that it was a game until I saw replays (repeatedly).
The worst part for the team was that they lost composure once their leader was gone. CR scored twice on that PP, and it wasn't until after the 2nd intermission that the US looked like they had their heads back out of their straps.
Once Kronner got the A, he scaled back a bit on his hits (having been injured a lot over the years and just plain getting older might have been a factor there too). With Abby wearing the C, he needed to be more careful.
On the other hand, it was up to him to set the bar for the team and lead them, which I think is what he was trying to do.
He's no Claude Lemieux. He's just a guy who made an error in judgment. I hope he doesn't get suspended, but it wouldn't surprise me.
