Cassel and Calloway met and became good friends at a football camp in Washington not too long ago and currently play on the state's Badger 7-on-7 team together.
Cassel, a 2013 quarterback prospect who received an offer from SMU earlier this month and is extremely interested in the program, took it upon himself to get Calloway's film and send it to the Mustangs' coaching staff.
"Kolney sent them my film and then got back to me [last Thursday], saying the coaches wanted me to call them and so I did and I talked to coach [Tom] Mason for 20 minutes and he offered," Calloway said.
Calloway, who spoke with Mason last Friday, said the coach told him how much the staff enjoyed watching his game tape.
"He told me he really likes me on the defensive side of the ball and I'll definitely have a chance to play early and he thinks I'll be a great fit whether it be at safety or cornerback," Calloway said. "He said he's excited to have me down there."
Right now Calloway holds offers from SMU, Purdue and Colorado and says he's been hearing from the majority of the Pac 12, a few Big Ten schools like Penn State and Indiana, and a few ACC schools like Duke, North Carolina and Virginia Tech.
Though it's too early to pick a favorite, Calloway, who has a lot of family in the Southeast, said he does have his eye on Virginia Tech and UNC because he's always loved watching those programs.
"They were my favorites growing up," he said.
Calloway also has a bunch of family in the Dallas-Fort Worth area and was thrilled when he heard from SMU.
"It was really exciting, especially since I want family to be able to watch me play in college and I have a large amount of family in Dallas already, so it would feel like home being down in Dallas and it wouldn't be a hard trip [for my family in Washington] to make," he said.
Calloway said that SMU is "definitely" a school he's interested in and is "definitely" planning to take a visit soon. He mentioned that he and Cassel are talking about taking their visits at the same time.
He may live in the Northwest, but Calloway knew about and was interested in SMU before he received word from the program.
"I've done a lot of research on them prior to getting an offer or receiving any interest from them," he said. "Everything I know about them so far I really like, especially the fact that they're going to the Big East, which is one of the Big Six conferences. It'll be really good for me to play in a big conference."
Calloway has NFL aspirations and will choose the school he feels will best develop him to get to that level.
"I'm looking for a place that has a real family feeling to it and where I have a good bond with the coaching staff, especially my position coach and somewhere that the team will develop me to the best of my abilities because I plan on going to the NFL," he said.
"I also want to go to a school with great academics because if god-forbid I was hurt and wasn't able to make it to the NFL, I want something to fall back on. And that's something that coach Mason really talked to me about. He said the average salary for people who graduate from SMU is about $100,000," Calloway added.
While in the offseason, Calloway is lifting weights five days a week and running track, where he competes in the 100-meter dash and all of the relays.
"I want to make sure my speed and my weight work together," he said.
On the field, Calloway says his greatest strength is that he's a flat out playmaker.
"I get the ball in my hands a lot, whether it's a deflection or an interception," he said. "I also believe that I'm more of a corner-playing-safety, meaning that I can cover great, and can also play safety. And I'm not a safety that has tight hips and can only play safety and can't make the transition to corner. I think I'm very versatile."
"I've liked every school I've visited so far and they all have different things to offer that really intrigue me, and I've liked every coach I've met so far," he said.
Calloway has kept in touch with UW and WSU since his visits and said the coaches constantly tell him how much they like him and he feels like they could be close to offering.
Calloway plans to major in science, although he's not sure which exact field yet.
