A weak spot for the Denver Broncos last season was their offensive line. Without a solid group up front, the team — led by three quarterbacks, Demaryius Thomas, Emmanuel Sanders and CJ Anderson — struggled.
Denver started a rookie lineman at left tackle, which is the most important position on offense aside from quarterback. Garett Bolles was the guy. The Broncos drafted him to be a franchise player. Unfortunately, in his rookie season, he accumulated a bunch of penalties.
In fact, Bolles finished the 2017 season tied for the second-most penalties in the entire league.
