Except Costal wasn't an option team, they were an RPO team with the run option
against BYU pretty much always there.
So you like stats so let's go over some.
Costal's TOP was higher that year against only 3 teams, the teams that performed better against CC? Troy, Appalachian St, Georgia So, Campbell?! Man those are some defensive juggernauts!
What about rushing attempts? BYU let them rush 54 times, which was only 2 less than Texas St at 56 attempts.
What about rushing yards? Texas St at 406 yards was the only team that gave up more yards than BYU 281.
I guess a better stat would be rushing yards per attempt, for that year BYU gave up 5.2 yds per attempt which was 7th out of 12 teams, with Kansas, Arkansas St, Georgia So, and Appalachian St performing better.
Again BYU's offense didn't play very good, but your opinion of the defense wasn't as stellar as you made it out to be.
