our defensive line feasted on that iowa offense last year, and we've consistently won the line of scrimmage against them for years. if their line was getting away with so much, how come we've controlled those games? good players make plays regardless, and our edge rushers have always found a way to dirsupt. blaming the refs is a weak excuse for getting outplayed, which hasn't been our problem against iowa. their so-called advantage clearly hasn't been enough to beat us.
