Nembhard is already pretty well known in Canada, and he plays for Vaughan -- Andrew Wiggins' school and a Toronto-area power. He had a quiet outing at last week's All-Canadian Game (2 pts) but it's understandable given that he was one of the younger players in the game. He's a very skilled passer and has good repertoire of floaters and the like, kinda like a bigger X. Still very slight of build and an average athlete.
Oh... and another 2019 Canadian to watch is wing Rowan Barrett Jr.
He's at Monteverde so I wouldn't hold my breath, but he has a v nice game and extreme ups:
