They have a lot of new faces at WR and DB. Their new RB lacks break away speed and will be a pound and grind type of back.
Iowa is likely going to be the Iowa that we already know them to be.
Not sure where you’re getting the “new faces at WR and DB.” We return 3 of last year’s top 4 receivers (Nick Easley, Ihmer Smith Marsette, and Brandon Smith at receiver) and 3 of last year’s top 4 corners (Manny Rugamba, Matt Hankins, Michael Ojemudia). We lost Matt Vandeberg at receiver and Josh Jackson at corner. All our safeties return.
As far as running back, it will be two guys like we’ve done pretty much every year since you joined the Big Ten. Our thunder guy (Toren Young) had 8 carries for 21 yards and a TD against you last year. Our lightening guy (Ivory Kelly Martin) will be every bit as good as Akrum Wadley. Same guy. Had 6 carries for 90 yards and a TD against Nebraska last year.
We did lose a fifth year senior who’s waited patiently and was expected to challenge for a starting spot at linebacker in Aaron Mends.
You’re absolutely correct that you’ll know what to expect from Iowa though. Likely the best tight end group in the country, serviceable receivers, pound it out run game, a defense that rushes 4 and drops 7 that stops the run. Football the way it was meant to be played!
