The read
Model analysis · October 28 · refreshed weekly

SP+ rates BYU 16.7 (13th) against Arizona State's 2.3 (62nd), projecting BYU by 16.8 and an 85 percent win probability. The consensus line of BYU -16.2 and an 84 percent implied edge track the model almost exactly, with the ProphetX exchange slightly steeper at -660, or 87 percent. There is no real model-market disagreement to exploit: all three sources price the same roughly six-to-one favorite.

The unit ranks explain the margin. BYU pairs a 20th-ranked offense with a 20th-ranked defense, while Arizona State sits 66th and 53rd. Form reinforces the split: BYU is 6-1, its only loss 31-39 at UCF, with wins over Arizona, TCU, Iowa State and Notre Dame. Arizona State is 4-3 and volatile, alternating wins against Kansas and Kansas State with losses by 36 at Baylor and 28 at Texas Tech.

Season outlooks diverge sharply: BYU projects 9.2 wins and a 37.1 percent Playoff chance, Arizona State 5.9 wins and 0.3 percent. The series is even at 1-1, and Arizona State took the last meeting 28-23 in 2024, the lone thread arguing the number should not run further.

The model and market sit within a point of each other on a BYU favorite, and the ratings gap backs it.
