It's a good test for seeing how Frazier/McDermott zone holds up against one of the best RPO offenses in the league.
Dline getting wins is obviously going to be big, but if they can't the more important test will be whether LBs can stay disciplined...the 'slow to go' strategy instead of overcommitting to the RB at the mesh. Secondary will be fine I would imagine (provided they can tackle)...I think they'll bring Poyer down into the box a lot to bracket either Hill or Kelce.
