I thought Groshev stood out the most, continuing to get multiple chances and scoring one. I didn't notice Merela as much this game, but the announcer was terrible about mentioning any lightning players, so I found it harder to follow than previous games.
We need to see more as the preseason goes on, but right now I'd put Groshev ahead of Merela and ABB to make the team as he has size and looks like a better skater. He works hard every game I've seen to create chances. I can see him fitting on a third line more than ABB.
I think Eyssimont also had another good scoring chance very early in the game. Tomkins looked much more like an NHL goalie to me than Alnefelt. I'm interested to see more of him.
