I made it 45-46 but I'm not a huge totals guy..
I do not think ISU will score much but if I were under backer I would worry about IOWA adding on late which is un-ferentz like but special circumstances here with backup QB Stanley in need of some run. IOwa's defense will be playing with chip on shoulder as the Mia-Ohio yardage total was a little embarrassing and they have been hearing about it all week. Keep in mind, Iowa's best defensive player (no its not desmond King) the outlaw Josie jewell got thrown out for targeting very early in game. He will be back this week and very pissed off.
Also even though Iowa won this game last year it felt like they lost it due to the closeness and it kept coming up all year (i.e. "sure they are 12-0 but what about that close loss to shitty cyclones") so after a soft defensive performance last week and a chip on their shoulder after last years game, I think it sets up quite well situationally.
And dudes, Iowa States offensive line is terrible.. Iowa should win that battle by a mile. How is ISU gonna score? I think their only shot is to target stud WR Lazard 20+ times and sure that will be part of gameplan, good luck, as Iowa happens to have the Jim Thorpe winner at CB.. But it will be interesting because Iowa's defensive scheme does not have Desmond King (Thorpe winner) flip flopping side's of the field and I doubt they change that script this week.. What they do in essence is turn over half the field to King- thus allowing the safties to shade the weakside and make the field "small". If you are watching the game that is the first part to figure out. How will they use King vs Lazard.
Also, think I mentioned this in Big Ten thread but worth noting on these pages. Iowa defense did not blitz one single time last week. Goal was to keep it vanilla, especially after losing the outlaw, and give no useable film to ISU.
So to answer your question specifically, ya, I would lean the under, though I think the side provides many more outs. GL JDF
