Patrick Mahomes and the Kansas City Chiefs know winning consecutive Super Bowls is a tough task. They’ll have plenty of familiar foes and some new ones standing in their way of a repeat. The NFL’s road to Las Vegas starts next Thursday night when the Chiefs host the Detroit Lions after their latest championship banner is revealed high above Arrowhead Stadium. No team has won back-to-back Super Bowls since Tom Brady and the New England Patriots did it in 2003-04. Brady and the Tampa Bay Buccaneers prevented Mahomes and the Chiefs from winning two in a row three years ago.
