When Alex Smith had no options left, he ran. And he ran far.
The Kansas City quarterback carried the ball five times and gained 78 yards, including a career-high 49-yard scramble in the second quarter that set up his 12-yard touchdown run.
With a comfortable lead in hand, Smith settled into his usual role, throwing for 145 yards and a pair of touchdowns to lead the Chiefs to a 45-10 victory over the Detroit Lions at Wembley Stadium in the last of three regular-season NFL games in London.
"We got a lot of guys with a lot of different strengths," Smith said. "We can present a lot to a defense. It's hard for them to defend."
