In fact, he's a hoop star at Tallahassee (Fla.) Rickards, manning the team's point guard spot with his 6-foot-2, 186-pound frame en route to five scholarship offers on the hardwood including one from South Florida.
He gave football a shot in 2012 when he decided to play wide receiver, but injuries forced him to miss all but three games. Then came the spring and the switch to defensive back.
After three months of training at the position, Crumbie got the chance to camp at Alabama from Sunday to Wednesday and things began coming together.
"I'm pretty good at this, I made the right decision a few months ago to start playing corner," he said with a laugh. "The coaches showed me a lot of love on the first few days."
As the camp progressed, so did Crumbie's display of skills, which had the attention of both Nick Saban and Kirby Smart before he was named to the all-camp team.
"Kirby Smart said I'm one of the best corners in the country," said the rising senior. "Coach Saban loves me."
"They say I have great ball skills, long arms, great technique, and I picked up the defense fast," he continued. "They made a tape of me with 65 clips on it."
The pending evaluation could lead to an offer from the defending champs.
"They talked about it," said Crumbie. "But I'm not sure when. I had a meeting with Coach Smart before I left and that's what he told me.
"Multiple coaches on the staff told me coach Saban loves me."
The emerging defensive back left Tuscaloosa without an offer in hand, but Thursday brought plenty of unexpected news after word of his spring and camp performances got out.
The football offers have nearly already caught up to basketball in just 24 hours, and it's been enough for the two-sport standout to focus on the gridiron moving forward.
"I know that football is my future. It's what's going to get me to college," he said. "A brighter future."
Most football coaches that have evaluated him thus far agree with the versatile athlete, who said Alabama had a special message for him before he left town.
Said Crumbie, "They said I'm high on their recruiting board and I looked very good this week."
FOX Sports NEXT and BamaMag.com will track Crumbie throughout the summer.
