This will likely be a contrarian opinion, but I agree. Cozens gave us one very good offensive year as a center, and Tage gave us 2. But it required the team to play an all gas, no brakes style because they struggled so badly defensively.
This year, Granato tried to get them to focus on defense. Which, is somewhat understandable. They were never winning the Cup with their top 2 centers playing defense like that.
Problem is, it failed. Miserably. Cozens still sucks defensively, and now his offense is gone. And while there's been some improvement in Tage's defensive metrics, it's come at the expense of his offense.
The problem, in my opinion, is that neither player really has the defensive IQ to be a top 6 center. In that role, you're often left covering other teams' top 6 centers, and Tage/Cozens just can't do that. Having the ability to play defense at that level is a skill unto itself. And Tage/Cozens don't have it. Honestly, I've never seen any reason to believe either player can do that consistently.
Maybe I'll ultimately be proven wrong. Maybe they'll bring in a veteran coach who brings in some better system and yells at guys and stuff, and that gets them to try harder. Honestly, I'd be thrilled if they did. But I don't really see it. Fundamentally, I think they're just trying to jam square pegs into round holes.
The better move, in my opinion, would've been to keep Mitts, a player that can actually play well in all three zones, and try to add another one of him, so we can move Tage/Cozens back to wing. From there, they can simplify their games and focus on the things they do well (driving offense), without having to worry about covering the Barkovs, Points, and Hughes of the world.
