After one of the most incredible Rivalry Weeks in recent memory, we're down to 12 games left in college football's regular season: 10 conference title games, a rescheduled Cal-USC game in front of tens of people in Berkeley and, in another week and a half, Army-Navy.

With all due respect to Cal-USC, let's focus on the games that actually matter. With 10 conference titles and up to three College Football Playoff spots on the line -- Georgia is probably in regardless, but other spots must be clinched -- it should be an awfully exciting weekend. For each game, let's look at one particular key that could determine not only who wins, but who covers.
