I assume it is because most people here dislike Wisconsin more than Iowa, but I am more surprised by the love Iowa is being shown in these preseason rankings. If you look back at Iowa's season last year they finished 7-5 and ended the year getting beat at home by Nebraska and their interim coach. They easily could have lost to South Dakota State and should have lost to Minnesota. Even the Wisconsin game was very misleading as Iowa could not move the ball all day and a 3-0 Wisconsin lead became a 14-3 Iowa lead after a blocked punt and Mertz pick 6. Mertz and the Badgers punting unit basically gave that game away. Iowa doesn't come out of the '22-23 season 7-5 very often at all, would they be ranked if they finished 5-7? So a transfer QB and a transfer TE (a position they got great production from) are going to transform the offense? Then the defense is going to just stay at the same elite level minus 2 first round picks and a longtime starter (and 3rd round pick I think) at corner? Then you are going to get another amazing season out of the punting game too? I could see one of these things happening, possibly two, but all 3?
With Wisconsin, I can at least see the narrative. They added a QB that put up gaudy stats the last two seasons at SMU and return an RB that is considered elite. They added a number of highly regarded transfers at the WR spot as well. Then they replaced an interim coach with what most considered the biggest/best hire of the offseason in Fickell. They also lost less top end talent off their roster (Tippeman/Herbig) than Minnesota and Iowa. I could see how the season just went off the rails with the loss to Washington State and the firing of Chryst and that Wisconsin will be back to normal this year with a huge (on paper) upgrade from Mertz to Mordecai at QB.
I understand Minnesota not getting the benefit of the doubt that Iowa and Wisconsin seem to both be getting in the preseason rankings. Until the staff actually shows they can get over the hump, there is not a lot of reason to pick Minnesota to be the team that emerges from a rather murky field of West contenders.
