The Iron Bowl between No. 1 Alabama and No. 6 Auburn on Saturday will decide which team wins the SEC West, plays in the SEC championship game and remains in the hunt for one of the four spots in the College Football Playoff.
No. 9 Ohio State also will try to keep its CFP hopes alive when it plays at Michigan in the 111th version of "The Game" at The Big House on Saturday.
That's all well and good, but conference titles and CFP scenarios will take a back seat to another instate rivalry when it comes to bad blood, bitterness and downright venom.
