First, it is pure fantasy land to think that Iowa is going to blitz more. Norm Parker is Norm Parker. To think that Parker is going to suddenly, after 40+yrs, going to man up on the outside and blitz, is crazy talk. Same as all the 3-4 talk this summer. If Iowa is blitzing more that likely means they're not getting any pressure with their front and that likely means they're losing.
Second, every year there is this same group of people that "believe" Iowa will put up more points, they usually claim 30+pts/gm. Heck, if I recall correctly, even Miller claimed that the offense led by JC6 would put up 30+pts/gm. Iowa's offense is Iowa's offense, they'll average around 24-28pts/gm. The 2009 Orange Bowl season, Iowa averaged 23pts/gm. Last yr 29pts/gm.
Third, I'm not "doom & gloom", just realistic. This team has lost what, 15 NFL caliber players, to the NFL over the last 2 seasons. Iowa has a lot of good players but that's a lot to replace for Ohio St, let alone Iowa.
I think Iowa can win 8-9 games, but I also think that losing 6 isn't out of the question either. To sit here and know that Iowa has lost 15 NFL caliber players the past two seasons and think they're going to IMPROVE is just flat out blind faith.
