I’ve noticed the same things. BYU and the team’s they are playing just don’t have the “eye test” of speed and athleticism. It’s easy to notice it when I have so intensely paid attention to both Utah and their pac12 opponents. BYU can be physical and does have some size however. I’ll give them that. Their oline definitely has some big boys. Also, I wasn’t impressed with Boise St in their two previous victories, they, too lack that overwhelming speed and athleticism, and they lack the physical size and strength p5 teams have.
