AUBURN, Ala. (AP) — Alabama and Auburn are preparing for one of the biggest Iron Bowls in history. The top-ranked Crimson Tide and No. 4 Auburn meet Saturday in only the in-state rivalry's second Top-5 matchup. It's a winner-takes-the-SEC-West game between two-time defending national champion Alabama and another surprising contender. The only other Top-5 Iron Bowl matchup came in 1971. Bear Bryant's No. 3 Alabama beat No. 5 Auburn and Heisman Trophy-winning quarterback Pat Sullivan 31-7. Hundreds of RVs filled a lot down the street from Jordan-Hare Stadium on Saturday — even though campers can't stay overnight until mid-week. Tide quarterback AJ McCarron insists Auburn is merely "the next team in our way" whatever the Tigers' record. Tigers H-back Jay Prosch says it has felt like preparation for any other game so far.
