Just a little insight from an Iowa fan. Iowa has played 3 games, Miami (OH), Buffalo, and Iowa State. I'll give you a few stats for the 2 games against Iowa State and Miami.
Iowa's longest scoring drives in those 2 games have been 80 yds, 68 yds, and 66 yds. They've had to go less than 40 yds for everything else.
Their defense seems to be solid again this year. However it's hard to tell given their competition. Miami (OH) could be considered a test but Rothlisberger (sp?) had a terrible game with 4 int's.
Iowa State and Miami had success on moving the ball through the air against Iowa. I think Az State, with decent protection, will be able to do the same.
Also Az St held out 4 starters during their last game. A starting cornerback and safety.
Az State has killed their selves with penalties, turnovers, etc. in their first 2 games. On the flip side, i think Iowa leads the nation in turnover margin.
Mo Brown, who catches around 80% of iowa tosses is out for 3-4 weeks with an ankle injury.
Iowa run defense looks to be very solid.
If Iowas not able to run the ball with great success on Az State I don't see them scoring many points.
Does anyone have any comments about the Az ST defense?
Good luck.
