HOUSTON - There's a showdown in the Lone Star State.
High noon, Sunday.
On one side, the Houston Texans.
3 and 1, leaders of the AFC South.
Their weapon of choice: J.J. Watt.
On the other side, the Dallas Cowboys.
3 and 1, tied for leader of the NFC East.
Their 'pick' six-shooter: Tony Romo.
The big duel in Big D is expected to be an epic one, but the first shots have already been fired by the fans--in the form of mean memes.
