By “lines go south” I interpret as getting worse. Which could happen if Jenkins snaps like he did last season, injuries and or Sean Ryan or walker playing worse and replacements (Morgan, rookie) not ready to take over. Or others taking over and stumbling. Oline going north could be walker getting back to end of 2023. Jenkins improving on Myers’s. Banks improving run blocking. Ryan improving again because of competition or new guys are better than them. I think likely mild improvement at start of year with continued improvement throughout year depending on injuries. On defense who knows?
