I don't see why Dries would be the 1C right away. It will probably be some combination of Dries, Dickinson, Shvyrev, Toninato and Beaudin as the centers to start, with Dries shifting up and down the lineup depending on how the rookies perform. Shvyrev should stay at C no matter what though, both for development purposes and to maximize his effectiveness as a playmaker. The others can likely be moved to wing as needed, especially once Toninato gets his likely callup.
Greer - Shvyrev - Kaut
Agozzino - Toninato - Kosmachuk
Lewis - Dries - Beaudin
Barron - Dickinson - Nantel
Not that that guess matters much, it will likely be shuffled all around given that it's the AHL.
