Yes they blew the lead and lucked out with the missed extra point, but you can bet they won't make that mistake again. As for WSU, I think they'll beat Oregon.
I think cal is the better team and it's a bad matchup for utah. Utah has given up 8 passing TD's this year and their secondary is not very good. Goff will shred them. This will be a battle of offenses imo and I think cal will come out on top.
