It goes back further than that.

1992 Pat Dye "resigns."
1993 Terry Bowden's first year, AU goes 11-0
1994 Starts off 9-0 (beat #1 Florda), end up tying THUGA and losing to bammer. 9-1-1.
1995 meh
1996 meh
1997 SECw champs. Lose to Peyton Manning in SECCG.
1998 Dumpster fire. Bowden is fired.

1999 Tubs hired. average season
2000 Improvement
2001 7-5
2002 Tubs has most of his own guys now. A respectable 9-4 with wins over 3 top 10 teams (LSU, bammer, Penn St.).

2003 Tons of pre-season hype. People expected SEC champs and possible BCS title. Start the season vs. USC with Pete Carrol. Since the game was at JHS, everyone thinks AU has it. Nope, USC stomps us 23-0. Finish 8-5.

2004: AU goes 13-0 and should have won the MNC. USC ends up winning it (and then forfeiting it later cuz they paid Reggie Bush).

2005: 9-3
2006: 11-2
2007: 9-4 (with a loss to South Florida at home)
2008: Tubs decides to abandon the pro-style offense and hired a high-school spread offense guru (Tony Franklin). None of the other assistants liked him, Franklin had melt downs in the locker room, some say he and other coaches got into fist fights. Team fell apart. Dumpster fire. Tubs fired.

2009: Chizik and Malzahn hired. Decent season.
2010: National champs
2011: 8-5
2012: Dumpster fire. Chiz fired

2013: Malzahn hired. SEC champs/BCS title game (loss)
2014: 8-5
2015: ????

Basic pattern here is new coach is hired. He either kills it his first or second season (often undefeated). Then has a decent season or two after that, then a dumpster fire. Rinse and repeat.
