Those seven schools are the finalists for Miller's services. He anticipates deciding before Westlake kicks off their season in early September.
"I'm going to talk to my parents and my coaches and narrow it down to a top three, and then I'll decide from there," Miller said.
With his older brother Jimmy a redshirt freshman at USC, Miller said he's gotten advice from him, but no pressure to go or not go anywhere.
"He really had no preference for me. It would be cool to play against him. He just told me go where my heart is telling me," said Miller.
The unofficial tours took Miller around the Western part of the states, and each school had a uniqueness about them, he said. "It was cool to see the scenic changes. We'd go from the big city to the wheat fields. They all had their own special marks and were all really special," Miller said.
To end his trip, Miller took in a practice at UCLA and the Bruins are a very serious contender for Miller.
"It was cool being there (on Saturday). It was only the second actual college practice I've gone to, but it was high tempo and totally different from our high school. I got to see the players react to the coaches," Miller said.
Recruiting Miller to the Bruins is UCLA defensive line coach Thurmond Moore.
"Coach Moore took over after Coach (Jim) Svoboda started it. They are both really cool guys. I've talked with Coach (Karl) Dorrell on the phone and I get along with him and the other coaches really well," Miller said.
Miller said he hopes to have his decision made by September 1st. If not, though, he will take some official trips.
"I want to make a commitment relatively soon. But if I don't feel it, I'll wait and take some official visits until I know where I want to go. I don't have any set up yet. I do know I plan to go to the UCLA-Oklahoma game in September," said Miller.
Miller didn't attend any camps this spring or summer.
As a junior Miller recorded 60 tackles, including 14 sacks. He also had four forced fumbles and three recoveries. Playing both defensive end and tight end last season, he grabbed 16 catches for 183 yards and 1 TD, but this fall he'll be the Warriors primary target at tight end. Most programs, though, including UCLA, are recruiting him as a defensive end.
Academically, Miller has a 3.0 GPA and took the SAT on June 4th.
