I see what you are saying in a coach Mac moral victory sense. ISU had some close calls this year against K-State, Texas, and Texas Tech. Catching K-State in week 2 before they really got rolling (and possibly before ISU rolled over) certainly helped in keeping that game close. I think we can all agree that Texas was a below average team with a brand new staff that was still trying to figure things out. Texas Tech... well they went 4-8 and were a complete disaster this year.
There were 2 major problems with ISU that I don't know can be fixed in one off-season.
1. The defense. This unit was easily the worst in major college football. They couldn't stop anyone (the lone exception being Greg Davis and his prolific offense at Iowa :biglaugh::biglaugh::biglaugh::biglaugh

. Texas was down and they rolled this defense, Tech was down and they rolled this defense, Okie State was down and they rolled this defense, Toledo is a MAC team and they rolled this defense, NDSU is an FCS program and they rolled this defense, and Kansas which is basically a D-II program rolled this defense. Factor in the quality Big XII offenses and saying this defense got "rolled" would be the understatement of the century. I'm not sure there is a single player on the ISU defense that would be in the starting lineup for Kansas or NDSU and that speaks volumes. It's not just a lack of talent across the board either it's a lack of skill, a lack of athleticism, a lack of size, a lack of strength, a lack of endurance, a lack of awareness, a lack of discipline, a lack of fundamentals, etc... Basically in any area they can lack something... they lack it.
2. Inconsistent offense. While the offense has been somewhat better this season it has struggled when the chips were down and it mattered most. They jumped on NDSU and then limped to the finish, they jumped on K-State and then limped to the finish, they jumped on WVU and then limped to the finish, they jumped on Tech and then limped to the finish, etc... They looked great against Texas and then didn't bother to show up against OU or Kansas. Against Okie State when they had chances to stay in that game in the 2nd half the offense went to sleep on 4 consecutive possessions and what was a fairly competitive game turned into a blowout loss. I think most would agree that the offense played 2 complete games this season and those were against Texas and Toledo. Against the schedules that ISU plays every year the offense has to be more consistent. It's a lot to ask but clearly that is the more talented side of the ball for ISU and when games are hanging in the balance they have to deliver.
Combining a horrible defense with an inconsistent offense and you have the recipe for exactly what we have seen the past 2 years and what we will continue to see next year as well. It's unfortunate but that is life in the Big XII. You can't win with a terrible defense unless you are putting points on the board like Texas Tech or Baylor normally do.
