I think Smith is the 51st oldest player in the league this year
He's listed as 55th oldest, but that includes guys like Brent Seabrook, Shea Weber, Carey Price, Bryan Little. Guys that are technically under contract to play in the league this year, but who we all know are never gonna play again and for all intents and purposes are no longer active players.
This list also includes at least one guy that's signed to a two way deal, but is playing in the AHL and hasn't played a game in the NHL this year. Alex Stalock, Matt Irwin, Taylor Fedun, Brad Hunt, Steven Kampfer. All guys on two way contracts, but listed as playing 0 NHL games this year. All are in the AHL or possibly even call ups that have been healthy scratched.
Pacioretty is also older than Smith and he's listed as having 0 games played this year. I guess he's injured (what else is new?) again.
So basically only 45 guys older than Smith have played an NHL game this year. And there's like 700-800 players who will play at least one NHL game this year?
