I am usually very, very wary in this game. I hate betting the line, and got burned so many times on it that I have stopped doing so years ago. That said, this is the year to put money on Iowa and lay the 18.
I say this because Lanning is a TO machine and isn't accurate. In 7 career starts he has completed 57% of his passes, and has 6 career INT's in 7 games. Not only that but Lanning has some fumble issues and lost one vs UNI. Mike Warren also has fumble issues as well and lost 1 vs UNI.
One game does not a season make, but I didn't see anything from ISU that made me think they could hang with Iowa. If they would have been disciplined, but lost a hard fought game, I would be nervous. As it was the team showed a shocking level of poor discipline, bad decisions, complete coaching lapses (who tried to ice a kicking attempting a FG from the 2 yd line?? LOL). I don't think those types of issues can be fixed in a week. Take all of those issue and add on top the glaring lack of talent on that team, and it leads to a 21 point loss I believe.
