We're headed towards one of the best Iron Bowl games in years if oddsmakers are correct.

Alabama officially opened as a 4-point favorite to begin the week, and the line has moved to 4.5-points in some places. That point spread is the smallest in this series since the 2010 game, which was the only 1-point win in the past 20 years.

The oddsmakers' opinion of Auburn has been up and down this year. During the offseason, this game was given an early point spread of just a field goal. After the Tigers lost a low-scoring game to Clemson and again at LSU, the line swelled to double-digits. But immediately after the Tigers upset No. 1 Georgia two weeks ago, the line settled in at its current four points.

Home field has always been a major advantage for Auburn in this series dating back to the decision to move this rivalry game to campus stadiums rather than Legion Field in Birmingham, but the Crimson Tide has won three of the past four in Jordan-Hare Stadium. The only win for the Tigers during that stretch was the 'Kick Six' return in 2013.

That game, much like this year's version, determined the SEC West winner and gave Auburn the opportunity to play for a national championship.
