I don't think so. Just a year ago Kingsbury said he would retire if he couldn't call plays. I seriously doubt he would make a 180 degree turn in a year.
From Darren Urban
Excerpt from the article: Kingsbury was asked what it would take for him ever to give up playcalling duties.
"I would retire," Kingsbury said. "It's part of the game, I couldn't just sit there and watch it. A lot of people are great at that, managing games, and that's not my strong suit. My strong suit is calling it and interacting with the quarterback. I've got to play to my strengths."
