This will probably be the best Saturday of the college football season.
With four games matching top-15 teams, including No. 1 Alabama at No. 4 LSU, the stakes are high, the story lines intriguing and the playoff ramifications plentiful.
Both Southeastern Conference divisions could be settled if Alabama wins because the winner of No. 6 Georgia at No. 11 Kentucky in the SEC undercard will be East champions.
No. 12 West Virginia is at No. 15 Texas in a matchup of Big 12 contenders. The conference's playoff chances could take a hit if the Mountaineers pick up a second loss. The Big Ten has a similar game at the Big House where No. 5 Michigan tries to stay in prime playoff position against No. 14 Penn State.
Outside the ranked vs. ranked games, No. 7 Oklahoma faces a potentially tricky road test at Texas Tech. No. 3 Notre Dame is at Northwestern, with the Wildcats on a four-game winning streak.
Why wait for the weekend? No. 9 Central Florida hosts Temple on Thursday night in a battle for first place in the American Athletic Conference East. On Friday night, No. 23 Virginia hosts Pitt with first-place in the ACC Coastal on the line. Who would have expected that at the beginning of the season?
No. 10 Ohio State plays its first game since losing to Purdue, with Nebraska (fresh off its first victory) coming to Columbus. No. 15 Utah could just about clinch its first trip to the Pac-12 championship game by beating Arizona State.
There's a lot going on.
