I was going to mention this game. I was there - it was amazing! As a Royals fan it was pretty heartbreaking when they lost, but it was such an amazing game to watch. And honestly, a bit relieving when it finally ended. These kids are in great shape, but I mean how can you prepare for 5 OTs? They essentially played 2.5 games in a row. I can't imagine how they were still standing. And not to put down their trainers and staff, but I imagine NHL level trainers and nutrition experts etc. would be able to support them through it better.
It really felt like they should just call the game. The teams were clearly equal. It was a game 6 - it really felt like they should just give up and call it a tie, and replay game 6 later or just go to game 7. But you'd probably need both coaches to agree or something. And that would have been pretty unsatisfying.
I think the max should be 3 overtimes. At that point, you've played two games worth of hockey. If you haven't sorted it out by then... then you're tied. I dunno. Watching 5 OTs was amazing though and having an arbitrary cut-off would be pretty annoying, especially if everybody playing is willing to continue. But if there has to be a cut-off, 3 at least seems somewhat logical. But I'm sure every single player, coach, and fan would be super pissed off if that actually happened haha!
