He is mature enough and he is ready.

Creighton received a pleasant surprise yesterday with the early commitment of Canadian standout point guard Ryan Nembhard. Ryan has received a bucketful of collegiate offers and many had assumed his selection process would continue into the fall, given the lack of visits due to the Covid-19 epidemic.
Ryan has drawn a lot of interest his play over this past year, with several schools in the mix. His play in last June’s FIBA U16 Championships opened the eyes of many of the experts. Nembhard followed that up with sterling play this year in helping Monteverde Academy to the #1 spot in High School ball.
“With that, he’s drawn tons of college interest and offers. Many of whom would’ve taken him for either class but will now obviously accept the fact that he moved up one class.
“Stanford, Seton Hall, USC, Arizona State, (Florida, Ohio State) are among those involved,” he said. Also mentioned some new programs involved which include Creighton, Gonzaga and Maryland.” – Jake Weingarten, StockRisers
“The 6-foot-1 guard is a quick and tough-nosed prospect at the point of attack that makes everyone around him better. He brings great composure and a pace for the game, and is more than capable of defending the opposing team’s best ballhandler.” – Corey Evans, Rivals

Claude Nembhard (Dad) discussed the decision. “I just think that he is mature enough and he is ready. He has been playing up and has never really played his age. He belongs in the 2021 class and academically, he is really good so there is no need in prolonging it,” he said.
“Ryan is one of the premier guards in America at both pushing the ball in transition and putting pressure on the ball-handler full court,” Montverde coach Kevin Boyle said. “He’s a great student and leader.”
All indications point to the Jays picking up a great PG in Ryan and an excellent reload guy for the 2021 season. Ryan is an excellent start to the 2021 class. Way to go Coach Mac!
