Looking at FEI's program ratings, which encompasses the past 5 years, BYU plays:

15. Missouri
21. UCLA
24. Boise State
28. Nebraska
44. Utah State
47. Michigan
50. Cincinnati
57. East Carolina

That's 8 schools in the top 65 in FBS, with one FCS school and 3 G5-level schools.

Next year, we play:

8. Michigan State
21. UCLA
22. Mississippi State
24. Boise State
27. Arizona
31. Utah
41. West Virginia
44. Utah State
50. Cincinnati
53. Toledo

That's 10 schools in the top 65 in FBS. We're still missing one game (most likely a home FCS opponent) and a 1 G5-level school.
