If it's based on historical performance, I would suggest that we should expect 2-5 record. 

A win @Utah or @Minnesota would be a surprise. Although, I am not super familier with Minnesota and what players they return next year. 

I don't believe we have won a game at Boise yet either. So a road win there would be a surprise. 

We win about 50% of games against average non-rival P5 opponents - which is where I would place Michigan State and Missouri at home and Arizona State and Stanford on the road. So, that's where we get our two wins.

But, based on where the BYU program should be, I would say that we should be able to beat the two average P5 opponents (Michigan St., Missouri) at home and one of the average P5 opponents (ASU, Stanford) or Boise on the road. A road win over either Utah or Minnesota would be a surprise. So, 3-4.
