"I had been talking to Coach LaComb and Coach Nashif since I was in the ninth grade," said the 6-foot-3-inch, 185-pound Calvert. "I've been talking to them for a while long before I committed to Utah State and really liked BYU.
After committing to Utah State head coach Stew Morrell, Calvert later had a change of heart.
"BYU was recruiting me pretty hard all along," Calvert said. "When I committed to Utah State, BYU completely laid off of me for about a year. Then I decommitted from Utah State and [BYU] started recruiting me pretty hard again, so it didn't take very long once I decommitted from Utah State, but they had been on me for a while."
His decommitment from Utah State was risky, but it paid off once BYU started noticing him again.
"Well, I decomitted from Utah State and that was shortly before the summer circuit started for AAU," Calvert said. "Coach Rose and some of the assistants were out watching me play and they came out and watched a lot of my games."
"I then had an in-home visit from Coach Rose and Coach LaComb not last Friday but the Friday before that. That was when I said that I was committed to BYU.
"I was just really excited about the coaches and I really like Coach Rose. I also like the style that BYU plays. They play an up-tempo style and they play hard, and that's what I like playing."
BYU's basketball program under Coach Rose has enjoyed a rise in national prominence. Much of that exposure came by way of national player of the year Jimmer Fredette.
"He definitely had a big impact on the basketball world," said Calvert about Fredette. "BYU is known by everyone now and Jimmer had a lot to do with that. What I liked is how the BYU coaches handled Jimmer, and that was really good for me to see. They gave him a lot of responsibility and a lot of trust and allowed him to grow and do his thing. That was something that I really liked: watching him grow and become the type of player that he is."
Calvert hopes to come to BYU and make his own mark on the Cougar program.
"Coach Rose is pretty excited about me and said I would fit into his program really well," Calvert said. "He said I'm kind of a combo guard and can play either the one or the two positions, so they feel I can help the team at either spot. He just said he felt my style of play would fit into his program really well and he was really excited.
"I feel like I'm a pretty smart player and I can shoot the ball well. I also feel like I can see the floor well and the passes and run the team well. I feel I can bring a lot to the table at BYU.
"I feel I can handle the ball and shoot really well. I can also distribute the ball really well when I need to, or I can also score from the point guard position or the shooting guard position. I feel I'm pretty versatile.
"I like playing up-tempo. I can get past my guy and get into the fast break. I feel like my outside shot helps me get past defenders to be able to drive to the basket."
Calvert, who averaged 15.8 points, 4.8 rebounds and 3.9 assists last season as a junior, could very well end up playing point guard at BYU.
"On my high school team I play the one. Coach Rose told me that they were probably going to have me play point guard, but they were going to decide that once I got up there so they could see what my strengths are with the ball in my hands and playing off the ball. So it's just kind of up the air until I get up there and they can see everything I can do."
Calvert will join other notable recruits from the 2012 class such as Jordan Chatman, Nick Emery and T.J. Haws.
"I'm really excited about it and I think there are a lot of great players coming to BYU," Calvert said. "I think in a couple of years we're going to be really tough to beat. I'm really excited about it. I think we're going to have a lot of depth and I've seen how many of these guys coming in play, and I'm really excited to play with them.
Cougar fans will have to wait a couple of years before they have the chance to see Calvert in action.
"I'm LDS and the plan right now is to serve a mission right out of high school, and then I'll come back for the 2014 season," Calvert said. "That's what my parents want me to do is serve right out of high school.
"But, you know, I'm just really excited to be a part of BYU. BYU basketball has a lot of great history and hopefully we can keep the tradition rolling and have some great seasons down the road. I'm excited and can't wait to get out there and play."
