No. 11 USC and No. 18 Michigan are meeting for the first time as conference foes on Saturday as two of college football's most storied brands collide at Michigan Stadium in a Week 4 showcase. The Wolverines have already lost once on their home field -- taking a decisive blow from Texas in Week 2 -- and are seeking an offensive spark as they turn to the mobile Alex Orji at quarterback.

Here are the five biggest "must-watch" games on the docket for this weekend. While this game may not be the most exciting, Arch Manning is scheduled to make his first start for the Longhorns. That alone makes this game a must-watch on the schedule to see how he can perform.
