Beating Iowa’s defense is simple in theory, hard in practice. Good feel for the zone from your skill guys, accurate throws, and staying patient and not getting greedy. Teams that have the discipline to do those things play after play and not get into bad down and distance through penalties beat that defense. Also you have to remember that they are looking in the backfield so you better be able to use your eyes to move the safeties.
Maybe.........it seems to me the teams that beat Iowa almost every year are the teams not afraid to lose. How many times does a team like Purdue (who most years has no business beating them) light them up? You cannot play "not to lose" football against them. Even Danny Mac.....the dean of playing not to lose knew this.
