Patty Marleau is not only on the verge of playing the most NHL games in history, he's also less than a season away of playing the most consecutive games in NHL history (or second most, if Yandle also doesn't miss a game) (possibly third most, if Kessel plays longer than him and also doesn't miss a game).
To put things in perspective, he hasn't missed a single game since sometime during the 08-09 season. He's played every single game on every team he's been with for the last 12 years and counting.
