The rising senior weighed all of his options and found that Arizona was the best fit.
"After thinking about all of my other options and going through the information of all of the colleges that wanted to give me the chance, it was the best decision for me," Colacion said.
"Having been able to go to Arizona and meet all the coaches and giving myself time to think about it, this is the best decision."
For the linebacker, location and coaching were two of the final factors in deciding to end the commitment.
"The all-around mixture Arizona brought was what did it," Colacion said. "Being close enough to home for my parents to come see me play and still playing in the highly respected Pac-12 conference.
"They have great players and coaches there. The coaches are coaches, but they are also great people, so that helps a lot."
Rod Smith was the lead recruiter for the linebacker and reached out to him as often as possible with conversations that even went outside the football realm.
"I think I have a great relationship with (Smith)," Colacion said. "He messages me on Twitter at least once a day when he is allowed to, so we are always talking back and forth. He was one of the first people I called.
"We talk about food a lot. He was giving me some pointers on places to eat in Tucson, especially the Sonoran Dogs."
One thing that helped the Wildcats in the recruitment was a visit to Tucson that Colacion took earlier in the summer.
"The visit was awesome," he said. "It was even better than I expected. The facilities are insane and we got to meet all of the coaches face-to-face. I wasn't disappointed at all.
"Matt Dudek hosted me when I was down there. He does a great job and he's a really cool guy."
When he finally gets to campus, the Arizona coaches have a good idea of where they would like to see Colacion.
"Coach Casteel told me that he sees me playing the WILL backer spot and that is exactly what I play right now in high school," he said. "I thought that was really cool, so I can just focus on that spot moving forward."
Colacion still has one more year of high school left, so he will use the time to his advantage and work on a few aspects of his game.
"I would like to improve on getting better on my blitzes and using my hands more," he said. "That is really the main thing besides getting stronger."
Now that he is committed, Colacion can't wait to get to campus.
"I'm just excited to be a part of the program," Colacion said. "I just can't wait to get down there and contribute."
