Finding BYU on them is irritating because they require me to hit another button to show 51-100, but I did another post today showing how similar Scout/Rivals are for BYU's rankings.

Basically here's how it breaks down:
2011- Rivals is 7 spots higher than Scout
2012- Rivals is 10 spots higher than Scout
2013- Scout is 4 spots higher than Rivals
2014- Scout is 6 spots higher than Rivals
2015- Scout is 1 spot higher than Rivals
2016- Rivals is 1 spot higher than Scout
2017- Rivals is 3 spots higher than Scout
I didn't include 2018 because they have different commitment lists (Scout still has Hall committed) so it's not an equal comparison. So over the past 7 classes the difference is 10 spots in favor of Rivals, or 1.4 spots difference, on average, in Rivals favor.
