I'm rooting for Florida because I'm frankly tired of hearing about the Canadian element of this series, like Canadians are the only people on Earth who know, understand and appreciate the game. I've been watching hockey in general and the Penguins in particular since the mid 70s, and watched my nephew play travel hockey all over the East and Midwest and Ontario for over a decade (he now is an official who is moving up the ranks), so I know the game as well as any Canadian.
With that said, Florida looks like a spent team, and I believe that if they win, it almost will be a fluke of some sort. Also, I also believe that when you give a generational player in any sport the chance that McDavid now has, he usually seizes it.
