The only thing I'm going to say about Richards at this point is it's both clear that Sutter doesn't know what do do with him in regards to his usage and I'm not sure Richards knows what his player identity is right now either.
If you're a 4th liner, be a good 4th liner--don't lose your man, win faceoffs, etc. If you're a 2nd liner, you need to produce. This season, he shows great flashes, but nothing consistently in any role. I'm not sure player and coach understand each other. Not literally--I'm sure expectations are communicated--but he's more effective in better roles with more minutes, yet why would you give him those when he can't be effective in a limited role? He's an enigma right now because some shifts he looks 100% the guy he was in Philly (there were two or three shifts tonight where I got him confused with Pearson for work ethic and speed), others he's by far the worst on the team. Part of that could also be linemates--some guys won't finish for him, and sometimes when Richards is in no-mans-land it's because he's overcompensating for someone else's goofup which actually hurts the system.
Now that that's out--he's also only one broken gear in this currently dysfunctional system and even his biggest haters are going to have a hard time blaming tonight's 4 GA on him so please ffs let's chat about something else
