Here's a more recent comparable:
Yea. This is why anything departing from 6 by more than a game would be unreasonable.
Exacerbating factors for Rielly:
- It was after a goal as opposed to after a teammate being knocked out so maybe the NHL considers it more egregious to retaliate for a perceived slight as opposed to for believing someone injured your teammate.
- He skates further across the ice than Perron did.
Mitigating factors for Rielly:
- He didn't hit quite as hard/didn't leap up/toward the crosscheck
- It seemed like he caught more shoulder than Perron did
- Rielly has no disciplinary history as opposed to Perron havinh an incredibly minor one.
So those might adjust it a game either way depending on how the NHL weights them. But looking at the Perron comparable (which is incredibly similar and incredibly recent), anything less than 5 or more than 7 just doesn't make any sense at all.
