The Alabama defense took no chances in the rematch. When Jordan Jefferson dropped back to pass, he was swept under by a tide of crimson. When the LSU quarterback took off running, he must've felt like Alabama had a few extra players on the field. Courtney Upshaw, Dont'a Hightower and Co. sure made it seem that way. With a smothering display of old-school football, the No. 2 Crimson Tide blew out the top-ranked Tigers 21-0 in the Allstate BCS Championship Game Monday night.
