Don’t get your hopes up here. Half of the limited viewing periods did not include starters.
I will tell you that Justin Bell, senior returning starter at right guard, was grouped with the centers during the viewing periods.
This is something Bell predicted at the end of last season.
Hugh Freeze talks about his plan for Bell here. It includes guard and center:
Sophomore Rod Taylor was running first team at right guard, next to Ben Still at center.
The rest of the line included Laremy Tunsil at left tackle, Aaron Morris at left guard and Fahn Cooper at right tackle.
