Or at least that's what I'm saying now that I know that dude is Jim McMahon, the Super Bowl shuffling champion QB from the 1985-86 Chicago Bears.
McMahon has his own line of golf duds called Swang Wear and if you check out his web site, you'll see that his outfit Wednesdsay was downright subdued compared to some of the color collisions in his clothing line. But that seems to be the thing these days in golf. See also Ian Poulter and John Daly -- just don't look directly at the pants for fear of burning your retinas.
Truth is, I didn't recognized McMahon right off the bat. I was drawn to his funky shorts and floppy hat and thought it made a good photo. But when I chatted up he and his buddies, I got a closer look and recognized him as the former punk rocker leader of that great Bears team, proving that you never know who you're going to run into at Colonial.
