Jenkins, a 6-foot-2 defensive tackle, lost 20 pounds and weighs 310, and it added to his quickness and speed. It also led to a strong performance at Miami's camp, offer was extended and Thursday morning he called assistant coach Mark D'Onofrio and committed to the Hurricanes.
"I fell in love with the school," Jenkins said. "I loved the attention they showed, the way they treated me when I was down there and how trustful and honest they were at the beginning of the recruiting process.
"It feels good now, but it will feel 10 times better when I'm down there play for them."
Jenkins had a long-standing offer from Pittsburgh and also recently picked up offers from Maryland, Buffalo and Massachusetts, but he was also hearing from Alabama, Michigan State, Michigan, North Carolina, Ohio State, Georgia and Rutgers.
"Miami is really the one that stuck out to me," Jenkins said. "The coaching staff stood out. They've had success everywhere. They had success at Temple, they have some defensive lineman in the (NFL) right now, and it felt like the right fit."
However, Jenkins acknowledged without losing weight, he would not have earned the offer.
"Since my first day coming to DePaul, the trainer told me he was going to bust my behind to get in shape," Jenkins said. "All the credit goes to him. He did the actual work with me, and even after workouts he taught me to go harder, and how to move my feet and put me on a good diet plan and guided me to lose weight and become better.
"I'm faster, I have better feet, I'm stronger and I have more muscle on me right now then I have at any point in my life."
His commitment to Miami came a few hours after four-star safety and close friend Kiy Hester, who used to play at DePaul but is now at St. Joseph's-Montvale (N.J.) High, announced a top seven, which included Miami.
"Kiy is one of boys," Jenkins said. "Since I committed today, I'm definitely going to talk to him about it and tell him he should become a Hurricane."
