A pretty casual interview with Patterson with one answer that I think is telling.
“Just letting guys go make plays,” Patterson said. “All the best athletes in the country are getting put into open space, and there’s no reason why we can’t. We did a lot of good stuff this year, but I think we’re realizing how talented we really are -- and explosive we can be.”
Although that seems innocuous, I believe that does show frustration with the play calling. All the fans know it, and obviously the players known it too. It's just unusual in a Harbaugh regime to see it mentioned by someone in the program.
