7. Offensive line
Typically losing a six-time Pro Bowl left tackle like Joe Staley would be a devastating blow to an offense. The 49ers managed to replace him with seven-time Pro Bowler Trent Williams. He’ll start at left tackle, and there’ll be a new right guard after Mike Person was cut during the offseason, so there’ll be some continuity issues for the offensive line. However, they have a deep group of reserves to help fill any vacancies including Justin Skule, Shon Coleman, Daniel Brunskill, Tom Compton, Ben Garland and rookie fifth-round pick Colton McKivitz. With left guard Laken Tomlinson, center Weston Richburg and right tackle Mike McGlinchey all back, the 49ers’ offensive line should once again be very solid.
