Did you watch last years game at all? DJK was good, but Reisner/Herman did far more damage to ISU than DJK did last year. I suspect that will be similar this year. Iowa's TE's are going to have a big game this season if ISU tries to key on McNutt, especially if the LB's are stacking the line as much as I suspect they will....you can take that to the bank.
As far as Coker "not being effective" carrying the ball 30 times, you may want to check out his stat line from the Insight.com bowl: 33 carries, 219 yards (6.6 YPC). Mizzou had a month to prepare for Iowa, knew they were going to run the ball, and look what happened. Mizzou had a much better defense last season that what ISU will have this season, and Iowa still pounded it right down their throat.
Iowa's OL has had one significant injury this preseason: Nolan MacMillan was the starting RG last year, and he will likely be out a few weeks with a sports hernia, but other than him, this is clearly the deepest OL KF has had since 02. I'm very anxious to watch it Saturday.
The only question mark I have for Iowa's offense this season is Vandenberg, but I've rarely seen KF give a player the kind of praise he's heaped on Vandy in this preaseason....I'm confident he'll be OK.
