BYU can win every remaining game on the schedule. However, we also have what I would call 6 'loseable' games remaining on the schedule (Utah State, Boise, Baylor, Wazzu, UVA and USC).
We won't lose all of them of course--or probably even most of them--but I also think it's unlikely we win all of them either. My guess is we lose 2-3 of those 6 games.
My advice: enjoy the journey. If you're just pining for the next game constantly you'll end up being disappointed deeply. Just enjoy the ride and cherish every win. As Bronco once said (and as we learned in 2017), it's hard to win a college football game. Enjoy them when we do.
