I'm not sure if a 7 win regular season qualifies as one of 8 win seasons BYU fans should be expecting (per your original post). However after the last two years 8 wins (with a bowl game) would be great, especially if BYU can improve on Kalani's 1-8 record against Utah, Boise St, and USU.
However if BYU goes 7-5 in the regular season, that will make three straight seasons BYU didn't reach the 8 win mark (a mark they reached 10/11 times from 2006-2016).
