"The main reason few outside the Texans' dressing room give them a chance of winning Sunday's divisional playoff game at Baltimore isn't the fact they have to play on the road against a team that was 8-0 at home this season and 21-3 at M&T Bank Stadium over the last three seasons.

And it's not because the Texans will be playing their first playoff road game and just the second postseason game in their history, nor is it because they've already lost at Baltimore this season, 29-14 on Oct. 16.

No, the main reason the Texans enter the game as 7½-point underdogs is their starting quarterback. In a round that features past Super Bowl-winning quarterbacks Tom Brady, Drew Brees, Aaron Rodgers and Eli Manning, the Texans are led by rookie T.J. Yates.

Yates, the only rookie starter still standing, is trying to become the first middle-round, third-string rookie quarterback to lead his team to two playoff victories during the Super Bowl era."
