It is very normal for byu classes to be rated higher on Scout than they are on Rivals, and Utah's classes to be rated higher on Rivals than they are on Scout. The main reason for this is that byu's main recruiting website has always been Scout based, and Utah's rivals based.
I don't believe I have ever seen Utah rated higher on Scout than byu, and usually byu's lead is substantial. Utah leading, even by a small margin, on Scout would show improvement on the talent of Utah's class
