Nah, it's natural for some games to "mean" more to a player than others. Last year's second half was insane. Some of those games felt like playoff games. Kovy went nuts. Game 38 of 82 when your team is in a playoff spot is not even close to as intense as game 70 when you're fighting to get in.
We'll see those in the playoffs for sure, and maybe towards the end of the seaosn if we get into the divisional race.
The only "sick" celly that we've seen so far was against the Caps when he scored on that PP. That game probably meant more to him because it was against his buds, Semin and Ovy.
