Here's the list as far as I know. Remember walk-ons are a little different. Iowa can't announce they're on the team because nothing is signed.
Preferred walk-ons are allowed to practice during August camp. The regular sort of walk-on isn't allowed to practice until school begins (last week of August this year?).
Jalen Chambers 6-5, 300, OL Bellevue High School
Cole Croston 6-6, 230, OL/DL from Sergeant Bluff-Luton
Andre Dawson 6-1, 220, RB Iowa Western Community College/Cedar Rapids Washington
Steven Ferentz 6-1, 220 OL/TE Iowa City High
Alex Imming 6-3, 205 WR Sioux City East
Will Kincart 6-3, 235 OL/DL/LS Davis County High School
Michael Malloy 6-0, 180-pound RB/WR Sioux City Heelan
Riley McCarron 5-9, 165 DB/WR/RB Dubuque Wahlert
Jeremy Nelson 6-2, 210 LB Sioux City Heelan
David Tann 5-10, 185 DB Cedar Rapids Washington
I'm assuming Steven Ferentz walks on at Iowa. I think the last time it was discussed, dad and Iowa head coach Kirk Ferentz kind of left it open.
"He's looking around here," Kirk said. "He's looking pretty hard at Iowa, as you might imagine. If that ends up being what he does,that's great. You know, we'll support him, whatever he chooses to do."
Kirk Ferentz also was asked a general question about walk-ons:
"We'd like to get our roster to 115, 118, somewhere in that ballpark," he said. "We'll know more after we get through spring practice to see who sticks with the team, who doesn't. We just had a freshman walk-on lineman retire a couple weeks ago. So, those things happen. Hopefully, we'll end up around 118, typically."Of last year's walk-ons, I expect former Solon kicker Marshall Koehn to have some sort of role, probably kickoffs if he can get the ball to the end zone.
