Tretter’s future at center: The Packers played the Ivy League standout at both right and left tackle during the weekend, but the possibility of sliding inside and playing guard and center is still in the cards. Tretter stands just 6’3″ and likely isn’t suited to play on the edges. Early on, he could provide quality depth at either guard spot while the Packers develop him as the future at center. According to Mike Spofford, Tretter spent portions of his pre-draft process learning the basics of playing at the anchor. Like so many of his new teammates before him, Tretter will likely be trained to play at a number of positions along the offensive line.
