Vikings receiver Stefon Diggs has speed to burn, but can he sustain it?

In a recent piece for the website the Ringer, Vikings General Manager Rick Spielman expressed his anticipation of all the player tracking data the NFL is making available to teams. One marker he specifically is looking forward to tracking is which players get slower as seasons gets longer.
Spielman might want to take a close look at the data for one of his players whose speed is his primary weapon: receiver Stefon Diggs.
Diggs had 849 yards and eight touchdowns last season and earned himself a five-year, $72 million extension thanks to his speed.
“His explosion when he is next to a defender, it’s uncommon,” Vikings receivers coach Darrell Hazell said. “His ability to create separation in a 3-yard box is what makes him really special. When he gets on the hip of a guy, the distance that he creates in a split second is what makes him very unique.”
The memory of Diggs racing down the sidelines to beat the Saints and help the Vikings advance to the NFC championship is a memory forever etched in the mind of Minnesota sports fans.
Just before reaching the end zone on that play, Diggs reached a maximum speed of 18.6 miles per hour, according to the data company Sportradar. That kind of speed, however, was rare for Diggs in the latter quarter of the season.

“Obviously, he’s one of the ‘A’ players, but it’s very important that you manage that throughout the course of the week,” Hazell said. “He’s a very excitable guy and energetic guy, so he’s got to make sure, and we talked with him about this all the time, making sure he controls the emotions before the game so his tank doesn’t get empty.
“His speed is one of his top three elements that makes him special and different.”
Hazell said Diggs’ fast-twitch muscle fiber is uncommon, even in the NFL. That fiber, which enables Diggs to perform in powerful bursts, is what allows him to create separation and maintain that speed down the field.
“It gives you space to make the play on the ball, and it also allows you to run after the catch,” Hazell said. “It’s not just a catch and the collision that allows you to advance the football. That’s what he was really good at with some of those catches.”

Diggs is a great athlete, one of the top high school WRs in the nation coming out. He can get open and his hands are huge. He's a revved up kind of guy and as the article states, save that energy for the field during the game and don't waste it pregame.
