I'm not going to read too much into Cozens partial season with the Senators. I definitely know the player a lot better than I did before, and I'm getting a sense of what he does well and what his limitations are. But being thrust into a playoff run, on a new team, new system - I wouldn't expect him to do more than keep his head above water. And I think he's done that.
I'm always reluctant to draw comparison around here (no comparison is perfect, no two players are identical, etc.), but I think an interesting example of how a guy with Cozens' profile can develop over time and in new environments is Jeff Carter.
This is a really interesting article that tracks Carter's trajectory. Basically, Carter was a big, right shot player whose biggest strengths - his shot, his skating, and his reach - were very similar to Cozens'. Carter faced similar "is he a centre or a wing?" questions early in his career, including playing stretches on the wing, but found his footing as a 2C once he got to LA, where the team's structure (along with his own development, no doubt) complimented what he did well as a player.
