Exactly six months ago, San Francisco 49ers quarterback Brock Purdy underwent surgery on the torn ulnar collateral ligament in his right elbow. The Niners and Purdy entered that day uncertain about when the former "Mr. Irrelevant" would return to football and, when he did, how he would fare.

On Sunday at Acrisure Stadium, Purdy offered answers to both questions in San Francisco's resounding 30-7 win against the Pittsburgh Steelers.

"Purdy shut some haters up [today]," defensive end Nick Bosa said. "I think whenever a guy comes back from an injury, people kind of don't expect him to make another leap in the second year, I'm just happy for him. He's exactly who we thought he was."
