The Sun Devils were one of the first programs to offer the four-star quarterback from Lehi, Utah, and the coaching staff put in another good effort by hosting Cooper and his family for the spring game weekend.
"The biggest reason why I went down there was to make that relationship with the new offensive coordinator, who I really liked and feel like we've got a good connection now," Cooper told Scout.com. "It was good to sit down with the coaches. We watched probably an hour and a half of film throughout the weekend, so it was good to go over their offense and talk football.
"I got a lot of personal time with coach (Todd) Graham. He spent a lot of time with me and my parents in his office, hanging out around all of campus. We went to Dickey's to eat lunch with him and then went to the spring game after. It was really cool."
The 6-foot-4, 200-pound Cooper visited Boise State and Washington State last week. Arizona State was the first Pac-12 offer on Cooper's list but, with new offensive coordinator (Billy) Napier joining the staff, the weekend served as an opportunity to find out more about his vision.
"The offense is definitely going to have you ready for the next level," Cooper said. "It's really a pro-style offense, just faster. Coach Graham said that, no matter what, they're planning to keep the same system in place.
"The biggest thing coach Graham was saying was that he's all in and I'm their No. 1 guy. His exact words were that I could go tell all the reporters that I'm his No. 1 guy, so I thought that was pretty cool just knowing they want me. It's good to know they just don't want to fill the spot."
Cooper is up to 15 scholarship offers and intends to take a few more visits in the coming months as he sorts through the options, with a decision scheduled for late spring or early summer. He completed 64 percent of his pass attempts for 4,059 yards and 38 touchdowns in 12 games as a junior last season, and has earned an invitation to the prestigious Elite 11 Finals.
