Philip Rivers' brother chooses LSU

At this rate, LSU is going to be done with its 2011 signing class by the start of the season.

The Tigers picked up their 17th commitment on Friday when quarterback Stephen Rivers, the younger brother of San Diego Chargers quarterback Philip Rivers, said he planned to sign with LSU.

ESPN rates Rivers as the country's 55th best quarterback prospect. His Athens, Ala., high school coach, Allen Creasy, said Rivers was further along than his older brother was at this point in his career.

"He's bigger. He's faster, and he throws the ball better," Creasy told The Baton Rouge Advocate. "That's just the truth. I think Stephen's potential and future are unlimited."
