Quarles, a 6-foot-4, 245-pound defensive tackle from Greenwood (S.C.), feels he rushed his pledge and didn't do his due diligence before making the decision.
"I want to find out who's really here for me and not just here to tell me that I'm going to play early and then end up getting up there and find out I won't be able to play until my sophomore or junior year," Quarles said. "And just try to earn trust in a coach."
Quarles says there's a "99-percent" chance he'll make a decommitment.
"Before spring practice, I'll let [South Carolina] know," Quarles said. "They'll still be in my options. But I'm just going to go back on the market and start looking again."
If he does de-commit, Quarles' first step is to take as many visits as possible. While no plans have been established, before it's all said and done he said he will likely visit Alabama, Florida, LSU, Michigan, UNC, South Carolina, Tennessee, and USC.
For his second verbal commitment, Quarles is looking to announce at one of the All-American games. He has already been invited to play in the U.S. Army All-American Bowl, but is holding out for the Under Armour All-American Game.
Education and coaching staff are the two primary factors in Quarles' collegiate decision.
"Education is first and foremost," Quarles said. "Once football is over, I want to know that I can go back on my degree and get a job.
"[I want] a good coach that's a man of God. [I want] somebody who's going to coach me and never give up on me [and] push me to my limit until I can't go any more. [I want to be] somewhere where I know I'm going to be taken care of."
According to Quarles, John Blake, his primary recruiter at UNC, fits those requirements.
"Coach Blake is a good Christian man," Quarles said. "I know his resume. I know he has the stuff to put you in the [National Football] League and to coach you and to take care of you when you get up there."
Quarles says that he and Blake speak almost every week.
Two former teammates of Quarles, Sam Montgomery and D.J. Swearinger, signed with two schools he's interested in – LSU and South Carolina, respectively.
"They might [affect where I go], but it's like I say ‘Every man has his own destination,'" Quarles said.
Quarles has received scholarship offers from Alabama, Clemson, Florida, Florida State, Georgia, Kentucky, LSU, UNC, South Carolina, Tennessee, and USC.
A second team All-State selection, Quarles made 75 tackles, including 21 for a loss and 17 sacks, last fall.
