At 6-foot-1 and 193 pounds, Elkins ran a 4.62-second time on his first 40-yard dash run. He came back on his second try with a 4.48-second run.
"That really caught me by surprise," Elkins said. "I felt I had a good day overall after that."
In other combine events, Elkins, a Charlotte (N.C.) Ardrey Kell product, vertically jumped 33.2 inches and benched 185 pounds 15 times.
"I went in there with confidence and I expected myself to have a pretty good day," Elkins said. "It ended up being a little bit better."
Elkins hopes to repeat his performance this Sunday at the Scout.com Combine in Charlotte.
Prior to Saturday's combine, Elkins was being recruited by Clemson, Duke, Maryland, Penn State, Tennessee, Virginia, and Wake Forest.
"I get a lot of letters [and] get invites to the spring games, but I haven't been offered yet," Elkins said. "I honestly think Duke is going to be the first to offer."
Elkins has already begun to reap the awards of his performance Saturday.
"Clemson has been contacting me a lot and I talked to one of their coaches [Sunday]," Elkins said. "And I heard North Carolina is now interested."
To continue improving his recruiting stock, Elkins plans to attend several camps this summer, including UNC's, Penn State's, and Tennessee's.
Elkins camped at UNC, as well as Clemson, last summer.
"[At the UNC camp, the coaches] were kind of interested in me at linebacker and the D-coordinator, [Everett Withers], talked to me," Elkins said. "I went over there and did a couple of safety drills, also because I can play either position."
Now, though, UNC is recruiting Elkins as a cornerback as he fits Withers' prototype for that position – tall, fast, and physical. Most schools, however, are recruiting Elkins as a safety.
After playing wingback in a reserve role as a freshman, Elkins started at linebacker for Ardrey Kell his entire sophomore season. Last season, he split time between safety and cornerback.
For this coming season, Elkins will start at safety, although the Ardrey Kell coaching staff has considered moving him back to linebacker. He will also pick up reps on offense at wide receiver.
Elkins doesn't have any true favorites, but a handful of schools have started to stick out in his mind.
"The education that you're going to get with Duke is attractive," Elkins said. "My family and I, we're all from Pennsylvania – my parents born and raised, I used to live in PA – so I wouldn't mind going to Penn State, either. I went up to Clemson with Prince [Shembo] and I went to Chapel Hill one day last year and really liked both schools."
Elkins has attended junior days at Duke and Wake Forest. He was invited to Tennessee's Junior Day, as well as Duke's Spring Game, but scheduling conflicts prevented both trips.
