LONG-SNAPPING HAS been described as the most specialized, and most ignored, position in all of sports. And in the strange, upside-down world of the long-snapper, the better you are at your job, the more anonymous you become. Case in point: Although they are a critical component in punting, extra points and field goals in a league where field position and scoring is at an all-time premium (especially during the playoffs), long-snappers didn't have their own official spot on the All-Pro team until last year. That inaugural All-Pro honor went to the Tennessee Titans' Morgan Cox.
