A week until voluntary offseason workouts begin, Pro Bowl cornerback Aqib Talib remains confident in the Broncos’ chances to defend their championship even as quarterback uncertainty exists.

“I think as long as the quarterbacks put in the work and listen to coach (Kubiak), if we put in that same work, I don’t see why we can’t repeat,” Talib said on ESPN’s SportsCenter on Monday.

Denver wants to add a third quarterback to compete with Mark Sanchez for the starting job. Brian Hoyer and Josh McCown are trade candidates, but San Francisco’s Colin Kaepernick commands the most attention. Does Talib think Kaepernick would fit?

“Who knows? We need to get him in that locker room and get him around the guys and see how it goes. (San Francisco) came to our facility last year (for dual practices during training camp), and he’s a good quarterback,” Talib said. “He has one of the strongest arms in the league, and we already know what he can do with his legs. (Kaepernick) has to be interested a little bit.”

Talib also called free-agent Johnny Manziel “a pretty good quarterback,” while noting the former Heisman Trophy winner’s offseason troubles. He said he wouldn’t have issue playing with Manziel, whom Denver is not interested in signing, but he stressed he trusts general manager John Elway to make the right decision at the position.

“It’s a good thing we’ve got John Elway. He does a great job of putting teams together. He doesn’t only bring guys in for their talent. He brings in guys on how he believes they will mesh with the team,” said Talib, who stressed the importance of the Broncos’ chemistry in helping them win Super Bowl 50. “I have been in locker rooms where guys get off work and you don’t see them. In this locker room, everyone meshes really well. That’s a credit to John Elway.”
