You need to be realistic about this. Iowa isn't Michigan State or Kentucky and can't afford to play that type of schedule. You need at least 7 or 8 guaranteed wins at home and the non-conference is only 12 or 13 games at the most.
If Iowa is already playing UNI, Iowa State, Texas/California, Syracuse and a high level team in the Big Ten/ACC Challenge, then you can't really pack in any more dangerous teams. That is 5 potential losses, so you need 7 cupcakes. The whole issue is make sure the cupcakes are ranked in the 150 range instead of sub 250.
Oh, I'm being realistic about it. The average final KenPom ratings of the seven home non-con opponents we had some discretion in scheduling for 2012 was 290. The average for the eight in 2013 was 288. One could argue that the more appropriate ratings to use would be those for the season that ended prior to scheduling those games, but by that method the average ratings were 292 for our opponents this season (excluding Abilene Christian, which wasn't even rated the previous year) and 297 for those we played in 2013. Our staff knew what they were doing in putting together those schedules.
To say we have a lot of room to improve our discretionary home non-conference schedule before we're at risk of taking a number of losses is an understatement. We've only played two teams with KenPom ratings of less than 200 in the last two years, and both of them were above 175.
There are a number of reasons the AD and the staff should be working hard to upgrade the schedule. One is to raise our RPI, which we should be able to raise substantially without damaging the overall record. Another is to actually get something out of the non-conference season other than glorified pickup games with 70% of our opponents. Playing any kind of organized, officiated game is a little better than practice, but it's much better for team and player development to play against teams that offer at least some kind of a challenge. Finally, playing so many chopped-liver teams does nothing for ticket sales and is somewhat unfair to those who do buy season tickets. Actually, the more important aspect of that last point may be how playing opponents like this affects actual attendance.
In addition to pushing our average discretionary opponent rating much closer to the 175-200 range (which still allows for a couple of dogmeat opponents to feed to the freshmen), I'd like to see the Hawks to start scheduling some home-and-homes with substantial competition. It wouldn't kill us to play two true road games against decent competition (including the BT-ACC or ISU game, which alternate road-home) out of the dozen or so non-con games we play every season. After all, we've recently traded one competitive road game we used to play every year by shifting the UNI/Drake game to a neutral site. By also losing UNI every other year as a home game, we've eliminated an opponent that didn't hurt our RPI to the extent our present level of discretionary opposition does.
I don't think it's a stretch to say that had we played a more respectable home non-con schedule the last two years, we might have made the tournament last year and avoided the play-in game this year.
