A year removed from having arguably the best offensive line in the Big Ten, Iowa will need to rebuild its signature position in 2010.
Kirk Ferentz is well known around football as an offensive line guru, thanks to his experience as an offensive line coach at Iowa and in the NFL. He consistently sends offensive line talent to the NFL and rarely needs to worry about that position's success.
But this year, Iowa must replace three starters on the offensive line. Tackle Riley Reiff is an All-Big Ten favorite and Julian Vandervelde is very experienced. The "next men in" have experience too, as they are all upperclassmen. But they have had little time on the field during their years at Iowa.
Although Iowa fans my dread it, this line has drawn comparison to the 2007 line, which sent quarterback Jake Christensen to his back way too many times.
That team went on to go 6-6.
The 2010 line is much more disciplined and experienced than in 2007, so don't expect a debacle. But again, anything can happen in college football.
If the line can't meet expectations, don't expect a debacle as big as 2007, mainly because the rest of the team is better. But the worst case scenario could still lead to heartbreak in Iowa City.
Worst case record: 7-5
