That would certainly be a good starting point. I think you could add another DT at times and run a 5-2 against run-heavy teams (e.g., Minnesota), and a 4-3 Under still intrigues me. But your suggested lineup is the most logical base with our personnel, and would play to their strengths.
I agree, they still have the personel to go heavy against a team like Minnesota but overall this is the line i would like to see the most of.
