From 2010-2013. Bronco is 8-11 against BCS conference teams and ND, not 7-11. I'm not sure why he didn't include this year's games in his argument. Oh yeah, because we won those games.
Since 2010, Bronco is 10-11 vs. BCS/P5 teams and ND. That is a .476 win pct. Bronco's record against BCS/P5/ND that finished with a winning record is actually worse than he stated through 2013. It is currently 4-8 a .333 win pct. (we'll see how Texas, Virginia, and Cal finish up this year)
He wanted to compare Bronco to Lavell. Lavell's record against "major" competition was 34-45-1. That is a .431 win pct. Against "majors" that finished with a winning record he was 15-36-1 a .298 win pct. Utah's record from 2010 to present against BCS/P5 teams is 16-20 a .444 win pct. Utah from 2010-2013 was 3-16 vs. BCS/P5 teams that finished with a winning record a .157 win pct.
Derik Stevenson's record against major competition when he was playing ('92, '96-'98) was 5-7. That is a .416 win pct. Against winning major programs he was 3-6 a .333 win pct.
From 2010-2013 Bronco is actually 12-15 a .444 win pct vs. FBS teams that finished with winning records. Lavell was 86-80-2 a .517 win pct. Derek was 13-12 a .520 win pct. Utah from 2010-2013 was 10-19 a .344 win pct vs. FBS teams that finished with winning records.
For complete context Bronco's first 9 years his overall record is 82-34 .706, his record vs. "major" teams is 15-19 .441, his record vs. winning "major" teams is 7-14 .333, his record vs. all winning FBS teams is 28-27 .509
