Vegas going craaaazy over LSU-Alabama

More bets have been received than for any other college game this year - and it could even top last year's National BCS Championship. No. 2 Alabama, which is playing at home, is favored over No. 1 LSU by 4 or 5 points - a spread that hasn't moved all week despite LSU getting most of the bets. So what's the story? From Business Insider:

There are two possible explanations. One is that professional wise guys are evening up the action by placing monster wagers on Alabama. Todd Fuhrman of Caesar's indicated that he's seeing sharp action on Bama earlier this week, and he thinks the line will move to make LSU an even bigger underdog by Saturday. Another reason the line isn't moving is that this game is being bet so heavily that Vegas has decided to set a line it's comfortable with and sick with it. Every square bettor in the world is going to have this game in their parlays and teasers -- essentially guaranteeing that the books will make money even if they are more exposed to an LSU cover.
