I think the punishment is a tad excessive, considering he also missed most of the Tampa game.
The nut shot was bad enough, but to go over after the fact and poke Dotchin in the face with his stick was awful.
Rask took some flak for faltering down the stretch (before righting the ship); by the same token I think Marchand deserves flak for doing these things, often at really inopportune times. His suspension before the Winter Classic not only contributed to an embarrassing loss, it soured what was supposed to be a major event.
I really hope his latest shenanigans don't contribute to the B's having to face Washington, and thus having a really short playoff.
His teammates bailed him out nicely against Tampa, and I'm sure they know his value to the team. But I cannot imagine they are happy about having to play these last two games without their leading scorer over something so dirty and meaningless.
