The 5-foot-11, 185-pound Phillips is happy with his decision.
"It feels good," Phillips said. "It feels like a lot of weight has been lifted off my shoulders, just knowing where I'm going to school."
"I'm really happy because there are a lot of people that get offers from anybody," he said. "I was just blessed to get that offer from them, and it feels good to know that someone wanted me."
The coaching staff played a big role in his decision.
"They were truly honest with me about everything," he said. "The coaches treated me like I was part of the family even before I decided to go there."
Being part of a new program also appealed to him.
"I like that I'm going to chance to be a part of the first team they've ever had," he said.
Phillips will play running back for the 49ers, but may redshirt next season. UNC-Charlotte will make the move to Division l after two seasons and that was also important to him.
"They may redshirt me next season because they will be Division l-AA for the first two years," Phillips said. "Then, I would have a chance to play Division l for three of my four years."
"The fact they are going to be Division l also played a big role in my decision."
Although he is committed, Phillips said he may visit some other schools before Signing Day.
"I would say I'm 90 percent committed," he said. "I still want to look around little."
Phillips finished the season with close to 1,800 yards rushing and 25 touchdowns. He also had over 400 yards receiving, four touchdown receptions, and a kickoff return for a score.
