"I had a blast," he told Scout.com about the weekend trip.
"I got to meet most of the coaches. Coach Stoops; he's amazing, he's a really nice guy and he's really into defense. He loves defense, loves the d-line. And the d-line coach played in the NFL for 10 years, he gave us a whole lot of information."
He described Coach Stoops as being personable and willing to help.
"You can go to him for anything," Melvin feels. "He'll really work with you."
Melvin, who emerged as the defensive line's MVP of the game, said he was proud of his individual performance this weekend.
"I only lost two of my one on ones, out of a total of about 20," he shared.
As far as his recruiting process goes, Melvin has made it clear that he has two leaders: Arizona and UCLA.
Is one school ahead of the other?
"No," he answered. "Both are tied in first place."
Even after referring to Arizona as a "dream offer" upon receiving the scholarship offer less than two weeks ago, Melvin admits that it is UCLA preventing him from making an immediate commitment.
So, what will determine which of the schools Melvin will be spending four years of his life at?
"The academics, the facilities, the coaches, and where I can see myself playing," he said.
When it comes to UA, Melvin claims he left Tucson impressed.
"I had a good feel," he explains. "I've toured the entire campus before and this weekend I really got to see the athletic facilities, see how their study halls are and stuff like that."
"It was great. The weight room was great, the stadium is great and they have a renovation coming up."
Melvin will be visiting Westwood on June 18th and also scheduling an additional Tucson visit before making his decision.
