Honestly, game 1 could have gone either way. Yes, the goal on Andersen wasn't amazing, but if he doesn't make a couple huge saves early on with some defensive lapses, then it would have been game over in the first period.
The thing I'm going to watch in game 2 is how Keefe can manage getting Matthews away from Jones and Werenski. Jones had his way with Matthews and that will remain the same unless you think outside the box. Throw Clifford on his wing for a shift or 2, double shift Matthews or make Jones' life hard by matching with the last change to get the 4th line with Jones/Werenski.
Matthews was engaged. Just time for the rest of the top 6 to wake up and get going.
