NFL-League-leading Patriots, Cowboys face tough games (Reuters)

National Football League fans have two intriguing matchups to savor on Sunday as the league’s top two performers, the New England Patriots and the Dallas Cowboys, both face tough opponents in Week 15. The (11-2) Patriots travel to Mile-High Denver to take on the (8-5) Broncos and their vaunted defense in likely frigid conditions, while the (11-2) Cowboys host the red-hot Tampa Bay Buccaneers on Sunday night. Led by four-time Super Bowl champion quarterback Tom Brady, the Patriots have won their last four games to tighten their grip at the top of the American Football Conference (AFC).
