Vick won't be given as much latitude as Roethlisberger, who has spent the past three-plus seasons working with offensive coordinator Todd Haley. Vick, by contrast, has been in town less than five weeks.
"We're going to work in his comfort zone and bring the game to him and put us in position to win football games," Tomlin said.
