I don't know how to link the article right now, but there is a good article on Arik Gilbert on today's ESPN.com. It basically said he did not tell his parents or anyone but he knew about a month ago (I assume when he took his visit Oct 5) that he was going to LSU. He said knew the media was saying UGA or Bama and he just played along with that and tried to keep his decision to himself all these weeks.
I would still like to know if Saban had an idea of that over the past few weeks, or if Gilbert outright lied to Saban and said he was coming to Bama.
With LSU's new offense, Joe Brady, the atmosphere, etc, unfortunately I can see this happening more often for LSU. They have always had the talent on D.
Each year it will still be Bama, LSU, and Auburn in contention for the West, but it looks to be much more difficult these days.
