I know Larkin has played great, but send him to GR and let him play 18 mins a night. We are still talking a very young player with only a handful of pro games. The standard to be called up should be the same for everyone in GR: When you are dominating, you come up. Keep it simple and stright forward.
ATM if Larkin stays in detroit he is going to be playing wing, not C. He is a natural Cman and needs to be developed as such. With Z, Richards, Sheahan, and Glendening already on the team, he isn't needed as a C. Let's get him 76 games in the AHL so that he is ready to play next year when Richards is gone.
