Fox, who hasn't even seen his quarterbacks practice, wants to see how all three respond to game situations.
"I prefer a gamer to a good practice player. ... I want someone who will execute under pressure in a game," he told <>The Post. "So much depends on what happens (with the length of the lockout). I honestly can't sit here and tell you when a starter will be chosen."
"Kyle is still the starting quarterback," Elway said at the time. "Tim is a very good football player. He's not a very good quarterback yet. We can make him a great quarterback. He's a young guy."
Orton passed for 3,653 yards and 20 touchdowns with nine interceptions last season, and he completed 58.8 percent of his throws in 12 starts.
Tebow, an icon at the University of Florida, generated excitement while starting the Broncos' final four games. He passed for 654 yards and five touchdowns on the year, and he rushed for another 227 yards and six scores.
Then there's Quinn, who was acquired last offseason in a trade with the Cleveland Browns for running back and "Madden NFL 12" cover boy Peyton Hillis -- a deal that has yet to pan out for Denver. Quinn joined his teammates for workouts last month, and said at the time that he sees himself as an NFL starter.
"I want to be No. 1," Quinn said. "I feel they (Orton and Tebow) both had a chance last year and I didn't get an opportunity. I'd love to get an opportunity to help us win games and get this team to the playoffs and see what happens from there."
"We've got three quarterbacks who have started games in this league," he said. "I know that quarterback is the top priority in Denver -- and there's a reason why they are so important because the great ones are so hard to find -- but I like the problem of having three to pick from."
