Earlier this season, Ben Roethlisberger openly contemplated whether he was too old, slow, and beat up to continue being an NFL quarterback. That came after the Pittsburgh Steelers were crushed 30-9 by the Jacksonville Jaguars. Since then, though, the Steelers as a whole have bounced back big time. They lead the AFC North with an 8-2 record and Big Ben even looks like he’s getting back to normal, despite being 35-years-old and playing in his 14th season as a starting quarterback.

During an appearance on 93.7 The Fan Pittsburgh on Tuesday, Roethlisberger fired back at critics who continue to wonder if his heart is still it.

“In a way it’s like, ‘Wait a second, you’re going to take a shot at me and you don’t know me?'” Roethlisberger said. “I’m going to go out here and bust my butt every day and be limping with bruises and put my body and my family through this and not care? You’re absolutely nuts.”

The Steelers are 5-0 since that loss to Jacksonville, with Roethlisberger 10 touchdown passes to just three interceptions in that time. He’s also thrown for over 1,300 yards during the winning streak, averaging 265.6 yards per game.

Roethlisberger remains under contract until the end of the 2019 season, but he’s not worried about the critics who call him “too old.”

“I’ve done this long enough, too, that I can let it roll off my back.”
