may not have been very much.

BYU had six solid P5 teams on the schedule. BYU was better than any of them that year (though maybe not by a ton), but they also started the season with 4 of them in a row.

If BYU has an average win chance of 65% vs their P% foes, the most probably outcome would be 10-2. With big blowouts over all of the lesser teams and victories over P5 teams from 3 different conferences, they would be a top 15 team. Add in a Bowl Victory and you are around #10.

On the other hand, 3 of the first 4 games were also on the road against P5 opponents. Had BYU lost the opener to Utah, going 8-4 would not be much of a stretch, especially if the first 4 games resulted in some injuries.
