Key players in LSU's passing game exuding confidence under new coordinator Cam Cameron

New LSU offensive coordinator Cam Cameron isn't ready to promise that quarterback Zach Mettenberger and his top receivers will be better than the collection of talented underachievers they resembled a year ago.

For now, the longtime college and NFL coach is only cautiously optimistic that the progress he has seen at practice bodes well for a regular season that begins Aug. 31 against TCU in Dallas.

Although Cameron says it's impossible to know how preseason practices will transfer to games, he says there is no throw Mettenberger can't make, and that the quarterback has worked hard to improve his mechanics.

Junior receiver Odell Beckham says LSU's passing game will be "spectacular."

Cameron says LSU's running backs also will have a "critical" role in the passing game.
