Although the Browns signed the Seahawks’ primary center of the past two years (Ethan Pocic), they are first attempting to see if one of their recent backups can claim J.C. Tretter‘s old job. Nick Harris is working as Cleveland’s first-string center during OTAs, Nate Ulrich of the Akron Beacon Journal notes. A fifth-round pick out of Washington in 2020, Harris made one start in each of the past two seasons — the late-2021 outing came when Tretter contracted COVID-19 — but he practiced extensively with the Browns’ first-unit O-line last season. Tretter dealt with injuries, and while the veteran played through them, he often sat out practices or worked in a limited capacity. This gave Harris a runway to full-fledged starter action and gave the Browns enough confidence to make Tretter a March cap casualty. The NFLPA president remains a free agent.

Ditching Tretter, 30, remains a gamble for the Browns, who still hold the NFL’s most cap space. Tretter graded as Pro Football Focus’ sixth-best center in 2021, started all but one game in five Cleveland seasons and provided a solid pivot on one of the league’s best lines. Here is the latest from the O-line scene:

• The ACL tear David Bakhtiari suffered on New Year’s Eve 2020 wrecked his 2021 season, limiting him to just one game (Week 18). The Packers are proceeding cautiously with their two-time All-Pro left tackle this offseason. Matt LaFleur confirmed the team is holding Bakhtiari out of OTAs, via ESPN.com’s Rob Demovsky (on Twitter), for conservation purposes. The expectation is the 10th-year veteran returns for training camp. Still, the lengthy recovery Bakhtiari required from his injury makes his status worth monitoring ahead of an age-31 season.
• New England picked up Isaiah Wynn‘s fifth-year option in 2021, guaranteeing the injury-prone left tackle $10.4MM this season. But he has missed OTA time, leaving recently re-signed right tackle Trent Brown — the left tackle on the Patriots’ 2018 Super Bowl-winning team — to fill in on the left side. The Pats have made a few trades involving contract-year talent under Bill Belichick — Sony Michel, Brandin Cooks and Jamie Collins being recent examples. If New England was to dangle Wynn, Jeff Howe of The Athletic notes teams would be willing to fork over a reasonable return (subscription required). That might be a bridge too far, considering the Pats already traded a veteran blocker (Shaq Mason) and saw Brown’s run of absences continue with eight more last season.
• The Bears have 2021 second-rounder Teven Jenkins pegged as their right tackle starter. Jenkins returned from preseason back surgery to start two games as a rookie, but he was close to 350 pounds last year. The Chicago blocker is back near his listed 320-pound weight, with Adam Jahns of The Athletic noting Jenkins is checking in around 325. Larry Borom is penciled in to take over for Jason Peters at left tackle.
