The only reason they shuffled at Center was injuries. Daniels missed spring ball, so Welsh got the bulk of the snaps, and that led to the staff to plan on Welsh starting in the fall.
Then Welsh missed a bunch of August camp, forcing Daniels to take the bulk of the snaps.
Daniels will likely be a 3 year starter at center, following Blythe and James Ferentz. It will be pretty incredible that we'll have 9 years of Iowa football with really just 3 centers (and a smidge of Tommy Gaul).
