Clyde Christensen mentored Andrew Luck and Peyton Manning before he became Tom Brady’s quarterbacks coach this season. Tom Moore worked with Manning, Terry Bradshaw and many others before the 82-year-old assistant got a chance to coach Brady. Christensen and Moore are quarterback whisperers on a staff led by Bruce Arians, who once wrote a book called: “The Quarterback Whisperer.” Having an opportunity to win a Super Bowl with Brady is an excellent way to cap stellar careers, though none of the coaches are ready for retirement.
