Ohio State's offensive line is one of the most talented groups in the country heading into spring practice, with four returning starters and several reserve players vying for snaps. The biggest puzzle is left tackle, which can set up all other pieces in the team's puzzle. Andrew Gillis highlighted that left tackle is the biggest puzzle piece, with potential solutions such as Ian Moore or Austin Siereveld. If Moore emerges as the best left tackle on the team, it could secure the blind side of the quarterback’s blind side and upgrade the right guard position. The spring is the first chance to find out who's an option where and who's ready to play where.
