The same principle applies to NFL offensive coordinators heading into their first season in the league. Ryan Grubb found that out the hard way last year. Coming to the Seattle Seahawks from a successful program at Washington led by a potent pass-heavy attack from Michael Penix Jr., Grubb made a lot of noises about fielding a more-balanced offense in the pros. Grubb abandoned the run early in the season and the Seahawks wound up putting an extremely heavy load on Geno Smith, who eventually buckled from all the literal and figurative pressure.
