COSTA MESA, Calif. -- It's not as if Los Angeles Chargers quarterback Justin Herbert hasn't been through this before -- new head coach, likely new offensive coordinator (or not) and likely new offensive system to wade through (or not).
He had three different head coaches (Mark Helfrich, Willie Taggart and Mario Cristobal) at Oregon before adjusting to a new staff as a rookie in the NFL last year. Herbert did alright, finishing his junior season in 2018 with 3,151 passing yards, then threw three touchdowns in winning the Rose Bowl to cap off a senior year in which he threw for 3,471 yards.
