Miller is twice the player at defense! If you move him to forward Fienhage would have to be the 6th defenseman, which is too risky at this point of the season. Miller is not the strongest in the defensive zone, but the offensive he provides on the blue-line usually balances out his defensive downside. Got to stick with Genoway, Jones, Finley, Blood, Miller, and Marto from here on out!
It is easier to hide inexperience up front than on defense!
