Lapierre got 5 games for his hit.
When you listen to Shanny's explanation, you could almost swap it out for Mcleod's hit on Kronwall.
The only real difference is that Lapierre was suspended before for a similar hit. If the league wants to be consistent at all (I know, I know), it seems like Mcleod will get fewer games. I'd guess three.
Similar, but Lapierre hit him from behind, but not in the head, add a couple games for the head hit for sure
