Youthful quarterbacks and underrated defenses help put me on the Under.
I'm not overly fond of UCLA's quarterbacks. Sophomore Austin Burton could be in line to make his second start for the Bruins in place of Dorian Thompson-Robinson, who has a leg injury. The Bruins remain without perhaps their most talented wider receiver with Theo Howard out. 
If you discount their games against Washington State and Oregon State, the Bruins are averaging 14.7 points in their four other games. 
Stanford's defense has come on. The Cardinal have given up an average of 20.6 points in their last three games taking on Oregon, Oregon State and Washington. The Ducks and Huskies each have top-30 offenses while Oregon State ranks 48th in scoring. 
The Cardinal are expected go with sophomore Jack West at quarterback with K.J. Costello sidelined. Stanford also is starting three true freshmen on its offensive line. An inexperienced QB behind three-fifths of an inexperienced O-line usually isn't a good combination. I'm sure the Cardinal will play conservative, which is the style of their coach, David Shaw, and run the ball frequently with Cameron Scarlett. That will keep the clock moving.
