Focus on each of their DB's (or linebackers) on each play... see how many callable defensive holding instances can be identified throughout the course of the game.
Heck, do the same for our DB's and linebackers. I'm sure there are uncalled instances of us doing it as well. I guarantee we would find a 3:1 or 4:1 ratio of Utah:BYU in a close study.
Do it for every Utah gam to firmly establish the behaviour pattern.
Send that to AD Harlan and Commissioner Yormark. Ask Yormark to make it a point of emphasis for the remainder of the season and next year to control this egregious play by the Utes.
