Tony Romo played the best game of his career.

He threw for 506 yards and five touchdowns in Dallas' 51-48 loss to Denver on Sunday. For three quarters, you could argue he out-dueled Peyton Manning.

With Dallas up 48-41, Broncos running back Knowshon Moreno tied the game with a 1-yard touchdown. Two plays later on the Cowboys' ensuing drive, Romo threw his lone interception of the game in the final two minutes.

The Broncos were able to capitalize with a game-winning field goal from Matt Prater with time expiring.

It's unfortunate for Romo because the mistake is the story from the Dallas side of things. It overshadows the otherwise outstanding performance from Romo during the afternoon.

At the same time, what's most important is how you end ballgames. Despite the statistics Romo put up for 58 minutes, his mistake in the final two was more important.
