Iowa last won a conference title in 2004, and has won one division title (2015). If the goal is to play in the conference championship game or win a conference title (as Campbell has stated is one of his goals), I'm not sure the Iowa model is the best way to go. The offense issues that trouble ISU also seem to nip Iowa at crucial times.
The team with the most points at the end of the fourth quarter wins the game, not the team with the most yards, or TOP, or body blows. IMO, the primary goal of the offense should be to score as many points as one can given the personnel that are recruited. This doesn't mean going full-blown air-raid, but is does mean not just scoring in the second half. The 3 first-half points against UT and 14 against TT are odd and troubling, given that those two teams don't really have good defenses, and given how the ISU offense turned up the scoring in the second half of both games.
And don't settle for tie on the road when your offense is rolling and your defense is struggling (I'm sure that fits into one of hoosman's categories).
