Iowa's defense played basically 28 minutes of the 2nd half very well. Then they went with prevent-style looks. But I'm not even asking specifically about today our how typically Iowa uses it.
Just in general, why do teams use it? I understand it's not give up the big play but it still allows easy 15 - 20 yard pass patterns. Three to five quick pass strikes (assuming the offense starts from its own 20 or 30 yd line) and a team can be in position to score while only using about a minute of game time. It just seems so ineffective unless there is less than about 30 seconds on the game clock and the offense has to drive most of the field while needing a TD.
