Alabama's recent dynasty has already entered into rare air. But this season, with another national championship, it has a chance to stamp its place in college football lore.
Only three programs have ever won three national titles in four seasons during the modern era (since 1936): Notre Dame (1946, 1947, 1949), Nebraska (1994, 1995, 1997) and now Alabama (2009, 2011, 2012). Nobody has ever won four of five.
"Because of today, with all the constraints and the level of competition has gone up, there are more good teams out there," college football historian Bernie Kish told CBS' Dennis Dodd of Alabama's run. "It's just an unbelievable feat."
Here's a look at some of the most memorable dynasties in the sport:
Oklahoma (titles in 1950, 1955, 1956) – The Bud Wilkinson-era Sooners are best known for that 47-game winning streak, stretching from 1953 into 1957, that still comfortably remains the longest in the sport's history. No other program has even strung together 40 straight.
Miami (titles in 1983, 1987, 1989, 1991) – Howard Schnellenberger created it, Jimmy Johnson groomed it and Dennis Erikson profited off of it. Three coaches, nine seasons, four national titles. And, man, did the Hurricanes do it with style, brazenly high-stepping and taunting their way into the history books.
