Of the teams that Iowa plays, Maryland has one of the higher yards per carry. Within conference play, they are tied for 3rd, averaging 4.5 yards per carry. For the entire season, they are 2nd, averaging 5.2 yards per carry.
Within conference play, they are 6th in the conference, giving up an average of 142.7 yards per game. It's hard to determine the merit of this number. On one hand, they've played Ohio State - which is a huge challenge to defend on the ground. On the other hand, Michigan is okay on the ground ... but that is due to philosophy and sheer determination and Penn State is only okay as well.
Overall, Maryland seems CAPABLE of throwing the ball ... but they also tend to throw INTs when they do so. They aren't terribly consistent through the air AND they lean heavily on the run.
The Maryland is highly "multiple" and will be a challenge to defend on the ground. They also have a lot of individual talent - although it doesn't yet appear like they play all that well together as a team.
My guess is that if Iowa can shut down their running game - then the Hawks should be able to win, perhaps handily.
