Why Cardinals Kyler Murray and Marvin Harrison Jr. are NFL’s next dynamic duo

GLENDALE, Ariz. — On first-and-10 from Arizona's 40-yard line midway through the first quarter on Sunday, Arizona Cardinals quarterback Kyler Murray rolled right on a play-action pass and scrambled toward the sideline to buy time. That's when Murray caught a glimpse of Marvin Harrison Jr. streaking toward the goal line.

The QB hit Harrison in stride, and the rookie receiver extended toward the goal line to complete a spectacular 60-yard touchdown.

None of it was according to script.

"That was really an off-schedule touchdown and Kyler just made something happen," Cardinals receiver Michael Wilson said after the game. "That wasn't really the route Marvin was supposed to run, nor is he supposed to get the ball on that play. But when Kyler is playing as special as he is, those kinds of things happen."

According to Wilson, Harrison was running a crossing route that's not supposed to go deeper than 12 yards. But Harrison felt open space deep because Murray got flushed out of the pocket, so he took his route higher for the big play.

"I kind of saw that pre-snap based on the play that we called," Harrison said. "I knew I had the over route. And once Kyler scrambled to the right, I felt like there was going to be nobody deep there. 

"Obviously, with Kyler and his ability to extend the play, you always have to be ready and know what you want to do if he scrambles. I just took it high. He had great vision and saw me, and we connected on a big play there." 

The touchdown was an example of the budding connection between the 27-year-old Murray and the 22-year-old Harrison, which Wilson expects to see grow and blossom over the next decade.

"Kyler is a world-class talent," Wilson said. "And No. 18 is a world-class talent, too. They
