The last time the Kansas City Chiefs faced the Denver Broncos, Kyle Orton was still a backup to Tim Tebow in Denver and Matt Cassel was the starter in Kansas City. But then Cassel injured his hand during the game and that set into motion, on the Chiefs' end of things, to pick up Orton once the Broncos let him go weeks later (it was Jay Cutler's injury that set the entire thing in motion).

But in that Broncos game against Kansas City, Tim Tebow had a passing game that ranks far from the greatest ever. He was 2-of-8 for 69 yards and a touchdown pass. That touchdown pass was a 56-yard strike to Eric Decker and the 17-7 lead. In the end, he got it done, but it's not a performance he wants to see happen again on Sunday.

Matt Bowen of the National Football Post believes, though, that Tebow is having trouble reading defenses right now and could be in trouble if the team is forced to throw:

However, if Kyle Orton can put points on the board for K.C., Tebow will have to make some throws vs. a secondary that can play man coverage.

But if the Broncos defense plays strong, we won't need to worry about Kyle Orton hurting his old team.
