BYU's SOS according to him for this year is predicted to be 40 whereas Utah's I believe is closer to 60 (I don't have the number in front of my but going off my recollection from what I was looking at last night). In terms of odds, I've seen various lines for BYU's over/under win total mostly being between 6 and 7. Most Utah projections I've seen are at 9. The 1 you are referencing has BYU at 5.5 and Utah at 9.5, but it seems like most have BYU at 6 or 6.5 with Utah at 9.
