His four Alabama titles have come in more concentrated period of excellence than Bryant achieved too. Four in seven, only Leahy's Irish can really compete with that. And you have to consider that they'd basically been a nonsense for a decade, since Gene Stallings, before Saban took over. And the margins of the last two seasons when they didn't win the title - the kick six and the semi-final Sugar Bowl. I'd say this is the most dominant dynasty 1A has seen, and it has been built in a hard division of a hard conference.
Clemson will be back next year though. 13 returning starters, including Watson. I think Bama only have seven or eight. And they have road games in Ole Miss, the Vols (who I think will put it together next year - they threw away some big games this season, otherwise they'd have won the east, and have a lot of returning starters), and LSU. And USC in Jerrytown for the opener.
