Even though they only had like 60 yards rushing. And Byu was poor against the run last year even though the average yard per carry defense was statistically very good.
The guy is prone to hyperbole.
This said, he's right that unfortunately Yewtah is a superior team to Byu on overall talent and depth, although the gap isn't as huge as he makes it to be and I think Yewtah is beatable, although the PAC South isn't looking that stout so they have a good chance of having only 1 or 2 loses.
