Given the offensive productivity of both Alabama football and LSU, a shootout is how the game will probably unfold. In that scenario, the team with a possessions advantage usually wins. The productivity of those possessions is the deciding factor.
When nearly every possession must yield points, field position also becomes a factor. Every component of special teams play, except points after TDs and field goals, affects field position.
Alabama football fans are never confident with Crimson Tide placekicking. It is scary to think a field goal could determine the outcome of the LSU game. Even missed PATs could be the decider in a game filled with touchdowns.
