I think that what's interesting about this season is how evenly matched the teams are nationally. Last weekend, seven of the top 10 ranked teams in the country lost to unranked opponents. And many others lower down suffered a similar fate, including one team up in Virginia that we know about.
What all this tells me is that the constant whine we hear at this site about how "The ACC has gotten much better then Tech while we've sat still! Obviously the universe is against us!" is, not to put too fine a point on it, horse-puckey. What has happened is that the entire conference (and many others too boot) has gotten more competitive. My guess is that, with a few exceptions that are characterized by the most blatant kinds of athlete exploitation and outright cheating (I'm looking at you, Nick), the entire NCAA has gotten more competitive.
Query: why has this shown up this year? For the ACC, I have an answer: almost every team in the conference has a difference maker or two that, with the right luck, can shift games in their direction. I don't know if this is what's happened everywhere else, but, from what I've seen on tv recently, it sure looks like it. So why has that happened? <Train whistle in the distance … wind blowing through the pines … crickets calling> Search me.
