INDIANAPOLIS — Tim Tebow is still Denver's starting quarterback, and coach John Fox is still OK with Brady Quinn being the backup.
The Broncos, though, are looking to add a few quarterbacks to the roster before training camp starts in the summer.
"We typically go to camp with four quarterbacks and right now we have two, so you do the math," coach John Fox said Thursday at the NFL's scouting combine.
It's unlikely the Broncos will use a high draft pick on a quarterback since they already have two young quarterbacks on the roster in Tebow and Adam Weber, and interest in bringing back Quinn, who is a free agent.
But there are now questions about how well Tebow and Quinn, last year's top two quarterbacks, get along.
On Wednesday, Quinn apologized for critical comments about Tebow that were published in a magazine article. Quinn said Tebow's success last season had a lot to do with luck and that he didn't think Tebow was too humble about demonstrating his faith.
On Thursday, Fox said Quinn's quick apology was more indicative of how strong the relationship between his top two quarterbacks really is.
"Sometimes this gets lost in translation, but I know their relationship is very good and they are good teammates," Fox said.
When asked about Quinn's apology, Fox said: "That just shows who he is. Sometimes that happens in conversation though it's never happened to me."
Tebow led the Broncos to the AFC West title after the team started 1-4.
CAM CAN: Panthers coach Ron Rivera realizes the bar has been raised for Cam Newton.
And he believes the No. 1 overall choice can exceed every expectation in 2012.
"The last three years, or four, he's had to learn a different offense," Rivera said. "Now he's going to have one voice, the same voice and I think that's important for growth."
But Rivera insists the reason for Newton's quick development last year wasn't because of sheer talent, and his improvement will come for one reason -- his work ethic.
"He was terrific in his development in terms of being the player we thought he would be, showing up early, staying late, doing the extra things that were needed, working certain things out on his own, coming to the coaches and trying to get as much help as he could," Rivera said. "I think the success he had was a lot sooner than we did expect from him but we felt the young man had certain abilities and he certainly did shine.
HOUSE OF CARDS: Cardinals general manager Rod Graves is aware of rampant talk that Arizona could be in the mix to land Peyton Manning.
He didn't rule it out Thursday.
Yes, Arizona seems happy with the quarterbacks already on its roster -- Kevin Kolb, Max Hall, John Skelton and Richard Bartel. But Graves did acknowledge the Cardinals are looking to improve everywhere and it could mean adding another quarterback. He is barred from talking specifically about Manning because of the league's tampering rules.
Hall and Bartel are both restricted free agents. Kolb and Skelton are under contract.
"Well, I think we are happy with what we have but as coach (Ken) Whisenhunt just said, we're about opportunities to get better," Graves said. "This is a competitive game, and we want to get better. If we can so be it. But right now we believe we have an outstanding group of quarterbacks and we're preparing to play with that group of quarterbacks."
