Week 4 is upon us and Pac-12 play is in full swing (with the exception of Washington State, which is home on a bye, and Oregon State, which gets Chris Petersen's old team). Here's what to watch (all times PT):
Friday:
No. 24 Utah vs. USC, 6 p.m., FS1
This week USC coach Clay Helton announced that redshirt freshman quarterback Sam Darnold would start against Utah. It'll be an uphill battle for Darnold in his first start for the Trojans, as he faces a blitz-heavy team. This season Utah has sent a blitz on 43 percent of its opponents' dropbacks, which keeps with the nickname of "Sack Lake City" (the Utes have 15 already this season).
