If Ruff trusts TNT at center (and Thompson plays well in his own zone at center), it frees up the line construction tremendously. TNT as 1C (the offensive guy) and Norris as 2C (d-zone, much better at face offs --- don't get hurt!) would be a good combination. McLeod is a very solid 3C and Kozak gives you responsible 4C play. Krebs and Östlund shift to the wing until more folks are healthy.
As the veteran forwards pieces return to health, you definitely send the kids back to Rochester for more minutes. Benson does everything Rosén does and better and Norris is an upgrade over Östlund.
