Quarterback: Zach Mettenberger is the starting quarterback of this LSU team heading into the 2013 season, no questions asked. But, who will be the Tigers' top backup?
Stephen Rivers and Rob Bolden are both very talented backups, and freshman Anthony Jennings enrolled early and will take part in spring practices as well.
Running Back: This should be a great spring battle to keep an eye on between three talented backs.
Alfred Blue was the Tigers' top back last year before getting hurt in Week 3 of the season. He was replaced by Jeremy Hill, who had an exceptional season, finishing as the Tigers' leading rusher.
In addition to Blue and Hill, Kenny Hilliard is another talented back who can run over opponents with his powerful style of running.
Wide Receiver: Odell Beckham Jr. and Jarvis Landry have established themselves as the top two receivers on this team, but who will fill that No. 3 spot?
Will it be Kadron Boone, James Wright or an incoming freshman?
We shall wait and see.
Tight End: This should be a great ongoing battle throughout the spring and probably into the summer and fall.
Travis Dickson is the top returning tight end on the LSU roster. Logan Stokes is a junior college transfer who will certainly help his stock by enrolling early this spring and getting in these extra practices. And then there is true freshman DeSean Smith, probably the most talented of the group, but he won't arrive until after the spring practices.
This could be the best, most competitive position battle in practice heading into this year.
Offensive Line: With offensive tackle Chris Faulk bolting early for the NFL Draft and the graduation of center P.J. Lonergan, who will step up on this LSU offensive line?
Will the Tigers move La'El Collins over to tackle and pair him with Vadal Alexander, who had an impressive freshman season in 2012?
Will Josh Williford and Trai Turner maintain the two guard spots, or will they get pushed by talented incoming freshmen?
Certainly keep an eye out on these offensive line position battles throughout the spring.
