I can see ISU remaining ahead of Kansas ... and perhaps even rising above Kansas State. IF they can pull even with West Virginia ... then that MAYBE keeps them ahead of Texas Tech and/or Baylor. However, the recruiting draw of Tech and Baylor is sufficiently high ... that with the right coaches, those teams are capable of being at TCU levels. Say ISU keeps their level of play up ... do they still win when their opposition takes them seriously?
There is a reason why Iowa lost to Purdue .... part of it was attributable to fine coaching by Brohm and Co ... however, another part of it was attributable to the Iowa squad making the classic error of not taking their foe seriously. When you drop your guard ... you set yourself up for defeat. I even know for a fact that Ferentz preaches that mantra to the team ... but you can lead a horse to water, but you cannot make them drink.
Does ISU still beat Oklahoma and TCU if the circumstances were different? Maybe .. but also maybe-not. Similarly, does Iowa beat OSU if they entered the game more sharp and more focused? Suppose Wilson wasn't stupid by thinking that OSU could just out-speed Iowa in the passing game ... had they run Dobbins more early, OSU likely tires out Iowa's D and keeps the ball away from Iowa's O (that was playing lights-out that night).
