According to FanDuel, the Alabama Crimson Tide is a 5.5-point favorite over the Oklahoma Sooners. ESPN's analytics give Alabama a 71.6% win probability. Four credible computer models predict an Alabama win with a winning margin as slim as one point to as high as 10 points. One lesser-known, but also solid model has Oklahoma as the favorite by a score of 21.3 - 20.6, correlating to the game ending in an impossible 21-21 tie.
Much is riding on the game's outcome for both teams. Alabama can lock down a Playoff berth and gain an SEC Championship Game appearance (subject to unpredictable SEC games' outcome and the SEC's byzantine tie-breaker rules).
