This time last offseason, the Browns went out and fortified their offensive line by adding right guard Kevin Zeitler and center JC Tretter in free agency.
Fast forward to this year, and it's unclear whether Cleveland will need to conduct a similar search at left tackle, as the Browns await a decision from Joe Thomas, who's mulling retirement following a season-ending triceps injury in October.

What about the draft?
The interior offensive line appears to be set, but the Browns need to address their depth at tackle, regardless of whether Thomas returns for his 12th season. Notable tackles in this year's NFL Draft class include Notre Dame's Mike McGlinchey, Texas' Connor Williams, Oregon's Tyrell Crosby, Oklahoma's Orlando Brown and Ohio State's Jamarco Jones.
