Can the Alabama Crimson Tide Defend Its BCS Crown in 2010?

The Crimson Tide may be headed into treacherous waters.

There has not been a back-to-back national champion in almost 15 years, and there have only been two teams in the past 30 years to accomplish that feat.

Alabama did it in 1978 and 1979, and Nebraska did it in 1994 and 1995.

Winning back-to-back national championships is one of the most difficult feats in sports, and winning back-to-back BCS championships has never been done.

Alabama now faces one of the most difficult tasks in college football—defending a national championship.
