The preliminary games are out of the way and it's time to dive into the main action of the college football season. September was full of many surprises-- both good and bad-- so we can only imagine what October will bring us, especially with the slate of conference games each week.

The marquee game for this week is a top-15 battle between No. 6 Notre Dame and No. 12 Clemson. Check out what to expect in this game and what other storylines Week 5 has in store for us.

Other storylines to watch:

Will Nick Chubb make history in Athens against Alabama? Entering the matchup with the Tide, Georgia sophomore running back Nick Chubb has rushed for at least 100 yards in 12 straight games. Chubb tied the Bulldogs record set by former Heisman winner Herschel Walker from 1980-81. It won't be an easy task for Chubb against Alabama, who has allowed the fourth fewest yards to opposing running backs this season.

How much offense can we expect between Baylor and Texas Tech? If we thought TCU-Texas Tech was an offensive shootout last week, just wait until Baylor and Texas Tech face off against one another in Arlington. Baylor has put up an average of 767 yards per game for nearly 9.55 yards per play. Texas Tech hasn't quite reached the 700 mark in any of its games but the Red Raiders are still averaging 594.5 yards per game. Both schools also rank No. 1 and No. 2 nationally in most plays from scrimmage totaling 40 or 30 yards.

Can Arizona and Oregon regroup after their weak performances at home? Sorry Ducks and Wildcats fans, there's no easier way to say that last week was embarrassing for both teams. Oregon suffered one of its worse--if not the worst-- losses at home in nearly 30 years and Arizona couldn't find an answer for UCLA. The Ducks face a surprising 3-1 Colorado team while the Wildcats have to play against a much-improved Stanford team.
