Johnson, who’s on a two-way deal, had some moments late last season as the Nets played out the string. For him, this summer is about doing what he can to earn a more secure opportunity, and nights like Saturday will help. Johnson was energetic throughout, providing excellent value as a scorer and defender. Brooklyn’s addition of Julius Randle was a sign that the front office intends to compete next season, but that does not mean Johnson has no chance of earning another shot to prove himself.
