Messier could be a passable color commentator, although not a particularly insightful one. He at least seems to understand what the role is and how and when he should interact. But Chelios is absolutely useless, and does nothing but laugh or talk over other people in the booth. And the two of them together just drag one another down even further.
Definitely. They bring out the worst in each other as broadcasters. The low point for me was when they were talking about NAK -- who they said was playing great, to their credit -- but almost immediately cut to the dude-bro, pseudo-bully quip, "Remember when he toe-picked with the Cup?" and spent the next 10 seconds chuckling like Beavis and Butthead.
Probably damn near every ex-NHLer has that in them, but having another guy in the booth encouraging it brings them both down. Not a big deal, but also not something you need another guy there to double-down on. If you need a 3rd guy, make it someone that's more of an analyst.
