Martinez went something like 20-22 passing against the hawks at kinnick last year but he is up and down. He was good last week against Wisky but also just heaved two terrible picks in the 2nd half. Really good running qbs give Iowa's defensive alignment fits and like last year with martinez throwing well and running their offense was tough.
If this new qb is not a very good passer then Parker will be or should be on full run penetration, gap assignment mode, not necessarily run blitz but a guy or two can go ahead and penetrate through where an offensive linemen pulls etc without worrying about a pass play.
Hawks stop the run well on 1st and 2nd force throws and smother them.
