The Steelers safety, working as a guest analyst for ESPN, garnered headlines earlier this week (link HERE) for saying Brady "sees ghosts" when pressured, but he struck a more complimentary tone Thursday.
Asked about which opposing quarterback was the toughest to face, Clark didn't hesitate.
"Ghosts or no ghosts, I have to go with the greatest living American, and that's Tom Brady," Clark said.
"You know, I said what I said, and I do believe it, and it's true. But when this guy has the opportunity to set up and throw the ball to his receivers, there's nobody better at pinpointing guys out and making plays for his team.
"I mean, he's a field general, he's a winner, he's a competitor, and Tom Brady, he's given us some hard times."
