At 6-foot-4 ½ and 316 pounds, Millington said he's been working hard to stay in shape this summer.
"I've lost 12 pounds recently," he said. "I want to be at 305 for the start of the season. I played my freshman year at 245, then I was 285 for my junior year. I want to lose some more because I'll be playing more on the defensive side of the football this year."
Millington, who plays in a summer basketball league a few times a week, also competed in track as a junior.
"I threw the shot 53-7 ½," he said. "I won sectionals in the shot and I threw the discus 164-7, which was good for 6th in the state."
Inside the classroom, Millington carries a 3.8 GPA and an 18 ACT score, making him a full academic qualifier.
"Mostly the Big 10 schools were calling last month," he said. "Miami also called me. I have [offers in the mail] from Oklahoma, Northwestern, Purdue, Illinois, Iowa, and Wisconsin."
Millington said he's taking his time with his decision, and has a different idea of what he'll do every day.
"I'm trying to keep my options open," he said. "I'm trying to consider all my options, and everything varies from day to day it seems."
Millington did talk about his feelings on the University of Miami.
"I spoke to coach Art Kehoe on the phone," he said. "He talked about getting me to come to camp down there, even though I won't be able to make it. But I told him I'll be taking an official visit there. I used to live in Miami in Pembroke Pines and we moved up here the summer before 8th grade. I come down to Miami about once every four months so going to the University of Miami for college would almost be like coming home since I have so much family down there."
"Miami hasn't offered me yet, but I guess it's because they haven't seen me in action yet," he said. "They'll get a look this season and will go from there."
"My goals this season are to get my 40-time down to a 5.0, bench 330 pounds, and maintain my body weight," he said.
