Scout's 42nd ranked 2017 prospect an 8th rared small forward, Samuels announced his commitment via Twitter.
"It was more than just basketball," Samuels told Scout. "Everything felt right and amazing while I was on campus. There's no point in waiting where you know where you want to be."
Winning and improving are two of Samuels' goals as a Wildcat.
"I expect to do my best and help the team get wins each step of the way," Samuels said. "I expect to get better and better along the way."
Samuels is known as an athlete with a high upside.
"Jermaine is an athletic slasher who had a tremendous month of July," said Scout Recruiting Analyst Brian Snow. "His versatility on both ends of the floor fit in very well with what Villanova likes to do on the court."
Samuels joins Dhamir Cosby-Roundtree in Villanova's 2017 class.
