The two best quotes from the article were:
Kubiak:
"We've got to work him out of some of those bad habits he developed as a pro," Kubiak says of Carr. "Already, I've put him through about three camps' worth of intensive instruction, which makes sense, because he had to make the most progress of anyone."
and
Carr:
"This offense is refreshing," Carr says. "It's crisp, and there aren't too many holes in it. It gets the ball out of my hand faster, and it always gives you a way out of every situation. The coaches tell us, 'When we call plays, we're guessing, but don't guess when you go through your reads. There will always be somewhere to go.'"
