WWE Hall of Famer Jim Ross has penned a new article for FoxSports.com commemorating The Undertaker’s 25th anniversary in WWE. JR says that The Undertaker will be an influence force in WWE for as long as he chooses and is the greatest tenured performer of all time.

The Deadman is alive and well behind the scenes of WWE and has been for years. How much longer he wrestles is anyone’s guess, but without question Calaway will forever be a part of WWE … if he so chooses.

When ‘Taker retires from his in-ring career is still to be decided, but when that day finally arrives — and it will sooner than later — the sports entertainment business will never see another like him.

From my perspective, Mark Calaway has replaced Andre The Giant and all other WWE superstars as the greatest tenured performer of all time.
