At this point in the offseason, teams use the remaining free agent market to address depth needs on their rosters. As a result, some view offensive and defensive line as two positions the Browns could use to make additions between now and training camp. However, May Kay Cabot of cleveland.com observes that the team is confident in its current options in both position groups. 
The Browns cut veteran center J.C. Tretter in March, saving the team significant cap space but creating a hole in the middle of the 0-line. They have signed former Seahawk Ethan Pocic, but the top candidate for Tretter’s vacated role is Nick Harris, who has made one start in each of his first two NFL seasons. If healthy, the team will also be able to return one of the league’s top tandems at both tackle (Jedrick Wills and Jack Conklin) and guard (Joel Bitonio and Wyatt Teller).
In terms of depth, 2021 fourth-rounder James Hudson is in line to remain the team’s top swingman. He played over 300 snaps as a rookie, making four starts along the way. While he struggled during his initial season, earning a PFF grade of 57.3, Kay notes how confident the Browns are that he will take a step forward after gaining experience at the NFL level.
The situation is similar on the other side of the ball. The Browns are high on the potential shown in spring practices by Jordan Elliott. The 2020 third-rounder has only made four starts so far in his career, but he took on a significantly larger workload last season, setting himself up to do the same this year. He could be joined as a starter by former first-rounder Taven Bryan, who signed a one-year deal in free agency. Kay also names rookie Perrion Winfrey as a candidate for at least a significant depth role.
Given their cap situation, the Browns could easily afford another signing along either the offensive or defensive fronts. Aside from any difficulty which could arise from convincing remaining free agents to come on a short-term deal (given the lengthy suspension expected to be handed down to Deshaun Watson, which could very well take the team out of 2022 contention), Cleveland already appears content with their in-house depth.
