Plax, whether a Steeler or a Giant, had a penchant for disappearing during the playoffs ... went from 6'5" to 5'2" in a heartbeat. Yes, he has the 1 catch you'll see on highlight films, but if you look at a game by game evaluation of the #1 receiver on the team, his drops increased, catches decreased and he had an ARod value to the team before last year.
His absence will only help the Giants, sadly enough ...
