Peyton Manning wasn't the only free agent who had a spectacular Denver debut. So did the man who denied him a second Super Bowl trophy and is now trying to help him hoist another.
Tracy Porter earned AFC Defensive Player of the Week honors Wednesday for breaking up five passes, collecting eight solo tackles and returning an interception for a touchdown that sealed the Broncos' 31-19 win over Pittsburgh.
It was Porter's NFL-leading third career game-sealing interception since 2009, including his 74-yard pick-six in the Super Bowl three years ago that sealed New Orleans' 24-17 win over Indianapolis.
''I've spent a lot of years locking receivers up,'' Porter said. ''I just had to make the best of my opportunity.''
Porter's five pass breakups marked the most by a Denver cornerback since Deltha O'Neal had six on Oct. 7, 2001, against Kansas City. And it was half the total he had all of last season, when Porter returned from microfracture surgery on his left knee to play in 14 games.
