4) The following teams are ranked much higher by the model than the BCS: Nebraska, Stanford, Arizona, Virginia Tech. Putting aside Virginia Tech for now (as noted in previous weeks' notes, this difference is mainly due to not counting AA games... though 22nd is probably too low for how well they're playing), let's look at the other three. All three have had very tough schedules to date, and all three have been dominant to very dominant, well beyond what you'd expect just looking at the W/L record.
Nebraska (48-13 @ KSU, 31-17 vs Mizzou) and Stanford (41-0 @ Washington, 35-0 @ UCLA) have a pair of extremely impressive wins which have substantially helped their ratings. Arizona doesn't have any single really exceptional performance, but have a number of very solid ones, such as the 41-2 blowout at Toledo, the 34-27 win against Iowa, and the 29-21 win @ UCLA (who's rated better than you'd think; 3-5 isn't great, but it's been against a truly brutal slate, and that Texas win still looks pretty good, though not as good as it did at the time).
There's also a fairly in-depth comparison of Stanford, LSU and Wisconsin (3 one-loss teams that the system rates much differently than the BCS) in the article, you all might be curious about that
