The Browns on Thursday officially began life after premier offensive line coach Bill Callahan, arguably the best in the NFL at his position.  They officially announced the previously-reported hirings of offensive line coach Andy Dickerson and his assistant Roy Istvan.  They replace Callahan, who left to join his son, Brian Callahan, the new head coach of the Titans; and former assistant offensive line coach Scott Peters, who took over as line coach in New England. Both hirings were previously reported.

Dickerson re-joins the Browns after spending the 2009 and 2010 seasons here under Eric Mangini as defensive quality control coach and assistant offensive line coach, learning his craft under highly-respected longtime NFL offensive line coach George Warhop.  He’s in his 19th season as an NFL assistant after spending the past three seasons with Seattle, first as run game coordinator (2021) and then as offensive line coach (2022-23). He spent the previous nine seasons with the Rams after serving in similar roles with the Browns and New York Jets.

Istvan, 55, spent the past five seasons as Eagles assistant offensive line coach, where he helped them set numerous franchise records and earn several individual honors. In 2022, the Eagles advanced to Super Bowl LVII while setting team records for points (477), total touchdowns (59), scrimmage touchdowns (57), rushing touchdowns (32) and total first downs (385). In 2021, the Eagles led the NFL with a club record 2,715 rushing yards. He helped coach center Jason Kelce, a Cleveland Heights native, to first-team All-Pro four times (2019, 21-23), while T Lane Johnson (2022) was a first team selection once and a second team selection twice in 2021 and 2023.
