I personally believe that they had Wilson play guard all year to give him reps in the league without the responsibilities of center. Now in year 2 he has those reps under his belt, knows how to be a starter and prepare as a starter, and just has to focus on (re)-learning the extra responsibilities of being a center and spending some time in the gym getting a little stronger and working on his conditioning. If Wilson beats out Bradbury (and I would hope he can), they will cut Bradbury and let him catch on somewhere else.
