"My dad and mom went there, so it is a family school for us," Morrison said. "I never really put two and two together and focused on trying to go there.
"My older sister is a gymnast at the University of Washington. We went down to Arizona when they competed and it was the first time I went down since I was like nine years old.
"We sat in McKale for a good two hours and at that point when I was watching I kind of knew because just the atmosphere for a sport that may not be as high profile as basketball or football, I could tell people really cared about Arizona. I think at this point when I was sitting with my dad and listening to the stories of him playing there, I knew I wanted to go there."
As much as Darryl wanted his son to go to Arizona, he never forced the issue.
"He kind of stayed out of it because he did not want to be biased, but he was really excited," Sam said.
"He said it was surreal because he never thought his son would play at the same school as him and hopefully I would do better."
Despite the fact his father played at Arizona, Morrison does not feel any added pressure.
"I know that the Arizona football my dad played for is totally different than the Arizona football I will play for," he said. "Obviously it is exciting and kind of a boost for me to try to do better and pass his goals, but I am another guy that is going to come work as hard as I can to get a spot.
"Obviously having a dad that played at all levels helps me in that pursuit and it is a blessing to play at the same school he did."
