Sixteen days before the first game, three spots on the offensive line are set.
Sophomore Cam Robinson starting at left tackle is as safe to call as any position on the team. Same with senior center Ryan Kelly, who begins his third season as a starter.
Senior Dominick Jackson at right tackle is less of a given, but he appears to be firmly entrenched just more than two weeks away from the season opener.
Then there are the guard positions, spots UA coach Nick Saban said in which there are two spots available for three outstanding players.
