Tampa Bay Lightning - New York Islanders
As I suspected, the Bolts had another gear. They destroyed the Islanders in game 2. Now it's up to the Isles to respond, but there's no final gear here I think. Trotz is already pushing them to their limit. If the Bolts can find their A-game again, I think we will see game 2 repeat itself. It's not a given that they can, but they have no reason to stop doing what worked so well. Tampa Bay wins!
In summary, because there's always a summary, my winners are:
Tampa Bay Lightning
