The Cleveland Browns closed out the 2018 NFL season with the second-best offensive line in the league, according to Pro Football Focus.
That ranking was accomplished almost completely based off the work of guards Joel Bitonio and Kevin Zeitler, and center JC Tretter.
Now, as the Browns start to work their way through training camp, Zeitler is with the New York Giants, traded for defensive end Olivier Vernon. And in a few months it could be Tretter who is spending training camp with another team as he is entering the final year of the contract he signed as a free agent in 2017.
