So Utah has beat BYU the last decade. Rest assured that not another soul in the country knows about that or even cares. Why? Because nobody thinks about Utah or sees them as a threat at all.
What then should you say to them? Remind them that for now they're the tallest little person in the state of Utah because on the big stage of college football they're ranked two spots behind South Florida and only 2 spots ahead of Appalachian St. Those names aren't necessarily feared in the world of CFB.
