The LSU Tigers' 2013 season depends on Zach Mettenberger.
The line between success or failure is hidden under the helmet of this star.
If Mettenberger plays like the quarterback fans witnessed in the second half of the Alabama game last year, the Tigers will be a national title contender. The array of talent and high-caliber coaching staff at LSU should handle the rest.
However, if Mettenberger plays like he did against Texas A&M and Florida a year ago, it's going to be a long season for LSU fans—immense talent or not. No pressure, Zach.
So with everything riding on Mettenberger in 2013, fans should know as much as they can about the man taking the snaps for the Tigers. Educate yourselves inside.
