I think Matthews looked a bit better playing with them because their pesky play drew attention and gave AM34 a little more space. However, outside of 1 game, he still looked like "playoff Matthews" which is a player who looks like he's playing down a gear and has historically scored 0.54 ppg in the postseason. It's not like he took their lead physically and became prime Eric Lindros, unfortunately.
The more I watch Matthews closely, the more he reminds me of a more lethal Rick Nash. Big, strong, and gifted... but he has zero dawg in him and is extremely soft for his size. This can fly on a random Wednesday vs. the Islanders... but come playoffs it becomes magnified.
