There's a decent chance that BYU and Utah both end up with four wins. I would say Utah gets at least five, maybe six and BYU gets four. But there is that possibility BYU ends up 4-9 and Utah ends up 4-8. That would be indeed painful.
As for playing for the seniors, they had their chance to get it done. Put in the the youth and let it roll. It's time to see the future play now.
