Then you'll find my current backline of: Goddard, Gibbs, Duffield, Dempster, Hanley, Bock interesting.
Yes, the Def Prems score less than the Mid Prems, but they come with at a discount price (dollar for dollar, not dollar for point), too. One of the things I like about loading your Def early, if you can find the value that is, is the margin for error is less. Take a mid Prem hoping that he scores 120/game and he scores 90 and it really hurts. Take a Def Prem hoping to get 95/game, and he scores 75 and it hurts less.
