Impending Letdown? Alabama is replacing virtually its entire defense. That may cost them. “It’s a mistake to assume that anyone can replace so many key defensive players without a hiccup. There are two recent parallels of powers that tried to replace eight or more starters: Florida in 2007 and USC last season. Both fell from the top six nationally in total defense into the 40s, and neither reached a BCS bowl.” [WSJ]
