He was the Cardinals starting guard and center in 2014, but with the acquisition of Shipley he will have to battle to try to keep his job.
Larsen is heading into his 6th season, and has played for Tampa Bay prior to coming to Arizona. He started all 16 games in 2014, and will most likely have to battle in order to be able to win the starting center position.
The coaches will have to assess who fits in best with the other linemen and make their decision prior to Week One.
It will be a great battle to watch in training camp, and may the best center win.
