Ellison cites his relationship with Rodriguez as being one of the determining factors.
"There wasn't one thing that made me commit to Arizona," Ellison said. "Overall, I just felt really comfortable with the coaching staff. They are down to earth guys who I didn't feel were just telling me what they thought I would like to hear.
"Obviously, I also liked their system and I feel I fit in well. I would operate out of the slot and return kicks."
Ellison expects to learn more about his future role when he takes his official visit in the coming months.
"A lot of the stuff they were telling me was just general things," Ellison said. "When I go on my official visit I imagine we will talk more about what they are specifically thinking about my future role there."
It wasn't just the coaching staff that impressed Ellison.
"I was surprised by how big the stadium was," Ellison said. "The facilities were very impressive, too. The coaches said that everything is going to continue to be built up, which is pretty exciting when you consider that everything right now looks really good."
Ellison is completely committed to becoming a Wildcat and is looking forward to becoming a student-athlete.
"I'm 100 percent sold on joining the University of Arizona," Ellison said. "This is the school for me and I'm happy my recruitment is over and I can concentrate on just getting better and I'm looking forward to applying to the business department there."
