Ben Roethlisberger is taking notice of critics who think he doesn't care anymore in light of his flirtation with retirement in the offseason.

Fresh off a four-touchdown performance against Tennessee, Roethlisberger said on his weekly radio show that such critics "don't know what they are talking about."

"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 on his Tuesday show, which is broadcast on 93.7 The Fan Pittsburgh. "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."

From the podium after Thursday's 40-17 win over the Titans, Roethlisberger was asked how his 299-yard, turnover-free performance felt. Roethlisberger said it felt good, then brought up the narrative from national media that he might be indifferent to the 2017 season.
