It doesn't take a genius 6 months to figure out that if Duke is playing Richmond the day Iowa is playing Montana, something could have been worked out for Duke to play Iowa and keep it in the 1-A family
Joey says the reason is money. I say it's a bit of fear mixed in with some conferences realizing this scheduling gimmick works to their benefit in overall record and poll performance. The answer, as is often the case, lies somewhere in the middle.
Tallying that up for the 5 major conferences, I believe that's 8 of the 12 SEC teams, 8 of the 11 Big 10 teams, 8 of the 12 Big XII teams, 11 of the 12 SEC teams (always leading the way!) and a stunningly low and almost bordering on respectable 5 of the 10 Pac 10 teams that have chosen to schedule non 1-A opponents this year. At least half of every major conference chickened out.
As always, the Pac-10 comes in most respectable (surprise!) among the power conferences. They backed it up by going to a round-robin schedule in conference once the 12th game was codified.
Some SEC honks say this is just beating a dead horse. Thing is, every year the same goofy schedules are made (I reckon that makes it a horsey resurrection), most heavily among a few conferences already enjoying the benefit of having more conferences foes than possible games.
The only way that will ever change is to make a big deal out of the issue---to get people upset and defensive on one side and angered and annoying on the other and let everyone suffer the agony of static and friction and shame to certain teams and conferences until a change is made.
This is the real cheating in NCAA football. We get distracted by the mischief of various cavemen and bad characters every team has. Instead of directing our energies to a greater good for the game, we get into our provincial/homer mindsets and let the real crimes to the game go ignored.
As an aside, whatever happened to the hat tip? When someone else links/alerts to material you're going to use, give a nod. Even if you enjoy frosty relations with the chap, they found it first---give a link.
