"Since joining the Chiefs late last month, Kyle Orton has been asked numerous times about the looming New Year's Day game against his old employers, the Denver Broncos, and Tim Tebow, the quarterback who took his job.Orton had been deflecting such questions, saying he was concentrating on the game at hand. But he had to confront it this week, with preparations for Sunday's meeting in Denver well under way."The only guys I'm trying to prove something to are my teammates," Orton said. "I really don't worry about anything else."You've got to worry about yourself. There's so much you've got to play for every week. There's still plenty to play for just for your 53 (players). That's the approach you've got to take."I value every chance I get to get on the field. You only get 16 chances a year to show what you've got."In Denver, the 8-7 Broncos are similarly trying to downplay the Orton vs. Tebow angle. The Broncos would win the AFC West championship and make the playoffs for the first time since the 2005 season if they can beat the Chiefs."I think that it's a little bit more for you than for us," Tebow said when asked about playing against Orton. "I think it's the Denver Broncos and the Kansas City Chiefs. That's a great rivalry, and it'll be a great game. Excited we get to play at home in front of our fans. I think that as a player, as a quarterback, as someone who has dreamed of that his whole life, it'll be exciting to have one game, one last game, one last opportunity to make the playoffs.""
