Offensive line coach Joe Gilbert runs the linemen through drills during the Arizona Wildcats' morning football practice ahead of the 2018 season.

New Tampa Bay Buccaneers coach Bruce Arians hired two of Kevin Sumlin’s assistants last week: offensive line coach Joe Gilbert and offensive analyst Harold Goodwin, both with strong NFL roots. It’s hard to imagine any Pac-12 staff having more capable offensive coaches than Arizona had in 2018. Goodwin will become the assistant head coach and run-game coordinator in Tampa. Replacing them with similarly skilled coaches will be a challenge.
