Here are some things to watch in Week 5 of the Pac-12 Conference football season:
GAME OF THE WEEK: No. 19 Oregon at No. 24 California. The Ducks (3-1, 0-1 Pac-12) are coming off a disappointing collapse after No. 7 Stanford rallied from a 23-point deficit to win 38-31 in Eugene. They face a stiff test in their first road game of 2018. The Bears (3-0) will be playing their first Pac-12 game after a perfect start in nonconference play moved them into the AP Top 25 for the first time since 2015. The key will be if Oregon QB Justin Hebert, among the national leaders in TDs and passing yards, can navigate against a Cal defense that's tied for second nationally with seven interceptions.
