I thought it was interesting to see the Massey Composite Rankings. The 3 most common computer rankings I see are Sagarin, SP+, and ESPN FPI. They have BYU ranked 49, 50, & 60, respectively.

However, the Massey Composite ranking actually has BYU at #42, which I actually feel is more accurate.

Here's where other BYU opponents rank:

8. Utah (L)
21. Boise State (W)
23. USC (W)
26. Washington (L)
44. San Diego State (?)
46. Tennessee (W)
48. Utah State (W)
89. South Florida (L)
91. Toledo (L)
99. Liberty (W)
129. UMass (?)
NR Idaho State (W)
