Darby, who is Scout.com's No. 1-ranked cornerback in the nation, is spending plenty of time texting, Facebooking and calling recruits.
"I talk to them and let them know about Notre Dame, and tell them why I chose Notre Dame," Darby said. "It's something I'm comfortable doing. I hit them up."
Another big time will be Darby's next visit to South Bend, Ind. He doesn't have a date set yet, but he wants it to coincide with a time when the Irish have other recruits on campus.
One of the reasons Darby can be influential in the recruiting process is his visibility, not only as five-star recruit as a cornerback and kick returner, but also as an elite performer on the track.
He won the New Balance Indoor Nationals 200 meter race in a time of 21.24 seconds, has run a personal-best 10.5 in the 100 meters and a few times clocked in below 4.30 seconds in the 40-yard dash.
"One time last year I got clocked at 4.28 so they made me run it again," Darby said. "I did and kept running close to it. I believe I can run even faster. I have to stay more narrow and keep it in the straight line."
The next few weeks figure to keep Darby busy on the track. He has the state championships and is heading to Puerto Rico to run in the 100, 200 and 4 X 100 meters.
But unlike many guys who run track and play football, Darby said his speed translates well to the football field.
"It helps me get from point A to point b faster than everyone else," he said. "It helps me play the game faster. Some people run fast in track and can't run on the field. My speed can translate. I can run fast both places."
