Once Booker grasped the system, it was time to address the little things. "The two quarterbacks throw totally different balls," he says. "Jay's a touch passer. A.J. [Feeley] zips it." He had daily tutorials with Sullivan, who showed Booker tape of other wideouts who ran a route better than he did. "I demand correct technique," says Sullivan. He saw Booker coming off the line lackadaisically on one route soon after the trade, and that afternoon he showed him footage of Boston and Anquan Boldin--receivers whom Sullivan had coached in Arizona--sprinting after the snap.
"The adjustments?" Booker says. "Football's been my life, and I've had to learn to adjust throughout my career. I had five or six different quarterbacks in Chicago. I wasn't a first-round pick, so I always had to work for everything. I couldn't use the excuse of a new quarterback or a new playbook. I'll be all right. I'll learn the corners in this division. What I really want is, at the end of this year, for people to say, That was a smart trade for Miami."
