Peterson's top speed in Week 10 explains why he's known as 'All Day'

Minnesota Vikings running back Adrian Peterson is also known as "All Day" because of the tireless effort he always gives. During last week's 30-14 win over the Oakland Raiders, he justified that nickname.

According to the NFL's "Next Gen Stats," Peterson's top speed in the fourth quarter was actually faster than his top speed in the first quarter (h/t @NFLNetwork).

He had 203 YDs & 1 TD. Max speed in 1Q: 18.86 mph Max speed in 4Q: 21.17 mph All day. https://t.co/K8Bh0MQTKj pic.twitter.com/g0zmCU0xZ4

While everyone else around him wears down, Peterson seems to get stronger and faster as the game goes on. He carried the ball 26 times against the Raiders, and his most explosive touch was his final one. With less than two minutes left in the game, the 30-year-old back ripped off an 80-yard scoring sprint.

That run put Peterson over 200 rushing yards for the day. If the game was extended for whatever reason, he probably could have kept running All Day.
