It takes time for a rookie to get adjusted to the NFL. But 4.21 speed is always going to be the fastest on the field.

When the Kansas City Chiefs moved up to draft receiver Xavier Worthy in the first round of the NFL Draft, the rest of the league had to worry. Putting a player who set the record for the 40-yard dash at the NFL scouting combine with Andy Reid and Patrick Mahomes was going to be trouble.

It took one touch for Worthy to make an impact. The Chiefs handed him the ball on an end-around and Worthy showed off his breathtaking speed. He ran right by the Baltimore Ravens defense for a 21-yard touchdown in the Chiefs' 27-20 victory in the NFL season opener on Thursday night.

Expect to see plenty more of Worthy simply shifting into high gear and making elite NFL athletes look slow.

Worthy got behind the defense for a huge fourth quarter play as well. After the Ravens cut the Chiefs' lead to 20-17, Mahomes found Worthy down the sideline for a 35-yard score, which Kansas City needed to hold off Baltimore.

There used to be a Chiefs receiver who looked faster than everyone else on the field. Tyreek Hill was watching and he was impressed with Worthy's speed after his first touchdown.

The Chiefs saw glimpses of Worthy's playmaking ability in the preseason. They were going to get him the ball in creative ways right away. The first touch became Worthy's first touchdown. He got his second score a little later in his NFL debut.
