I agree with his sentiment that basically their offense begins or ends with the OL. To me the rest (Goff, Gurley, the WRs/TEs) are dominoes that will fall- one way or the other- based on how much the OL improves. I do believe an offensive scheme plays into it as well which should help.

Personally I think going from Robinson to Whitworth is the biggest single position upgrade in the entire NFL this offseason. If Sullivan can stay healthy I believe he'll be an upgrade over Barnes. I have confidence in Havenstein. Brown at RT and their depth are the question marks right now to me.
