The most important positional battle this offseason might just happen with the centers. What's crazy to think about is that no matter who wins this battle, quarterback Aaron Rodgers will still be taking snaps from his fourth different starting center in four years.
By drafting Corey Linsley in the fifth round, the Packers either brought in competition for second-year player JC Tretter or they were simply looking for depth at that position. The more likely scenario involves depth, but Linsley might just have enough to push for Tretter's job.
What makes Linsley such an intriguing option is that he played almost all of his college football as a center. The same can't be said for Tretter, and it also wasn't true for former center Evan Dietrich-Smith. That experience for Linsley will take away a major part of the learning curve since he won't be learning a new position.
While the Packers will likely give Tretter the majority of first-team snaps in OTAs, Linsley seems poised to make some noise this offseason. Even if he doesn't take the starting job outright, don't be surprised if he pushes Tretter to the wall for his job.
