Defenses, including Kent State and Colorado State, think they have a blueprint for stopping Iowa. Put 6, 7, or even 8 guys in a box and just dare Iowa to throw the ball.
Iowa experimented with some different things against CSU to counteract this plan
1. Throwing to TE like Iowa always does
2. Running WR reverses, jet sweeps and mis-direction with mixed success
3. Playing speedy freshman WR to see if they are better at getting open. This also has had mixed results, but freshman keegan-Johnson did catch a couple of deep throws, including a 46 yard TD catch against CSU.
I have a hunch Iowa has a couple more tricks coming against MD to try to open up the offense.
