What a crappy defense we've had every year.
Iowa's defense only defends the line of scrimmage. Iowa's defense isn't capable of defending in man-to man-situations and passing situations. Iowa's defense primarily stops the '3 yards and a cloud of dust' offenses.
Finally (and maybe I buried the lead), we all know Ferentz is a conservative coach meaning he prefers the defense to stop the other's offense to win games. For example, Nick Saban, another conservative coach at Alabama, won a national championship in 2009 with an offense rated in the mid 70's nationally with Greg McElroy as QB and a strong running game. In 2011, Alabama had a more powerful offense that rated (I think) in the mid-50's nationally with Mc Carron as QB and a strong running game.
BTW, how were O'Keefe's offenses rated nationally? (Don't need to answer, it's a rhetorical question).
Through the years, the big difference I see between Iowa's conservative teams and Alabama's conservative teams is that Alabama has a much stronger defense in all phases of the game.
Why shouldn't Phil Parker be fired, instead?
