All opportunities to kneel (over the last 5 years)

BYU has had 31 opportunities to kneel the ball, which have resulted in

• 28 kneeldowns
• 2 times running the ball up the gut to kill clock
• 1 time scoring (this one is arguable if they could have run clock out by kneeling, depends on how slow they knelt and if Western Kentucky would have used timeouts while down 31 with under a minute remaining)

Utah has had 33 opportunities to kneel the ball, which have resulted in

• 22 kneeldowns
• 9 times running the ball up the gut to kill clock
• 2 times scoring (similarly, this assumes that San Jose St and Wazzu weren't going to use multiple timeouts to keep the game going with under a minute remaining)

The biggest difference seems to be that Utah will give backups carries and run the ball up the middle instead of kneeling

Opportunities to kneel in scoring position (over the last 5 years)

BYU has had 16 opportunities to kneel in scoring position, which have resulted in

• 14 kneeldowns
• 1 time running the ball up the gut to kill clock
• 1 time scoring 

Utah has had 15 opportunities to kneel in scoring position, which have resulted in

• 9 kneeldowns
• 4 times running the ball up the gut to kill clock
• 2 times scoring

Again, the biggest difference is Utah's willingness to run up the middle rather than kneel, though those 2 scores are worth noting - twice in 5 years when they tacked a TD on without really needing to do so.
