The Celtics’ offense looked uncharacteristically out of sorts during Friday night’s NBA Cup game against the Brooklyn Nets. It started out with missed shots, then turned into turnovers. However, strong games from Jaylen Brown and Neemias Queta, plus a bolt of energy off the bench from Hugo Gonzalez, gave the Celtics a chance to pull off a monster comeback win. Boston just couldn’t finish it off, thanks in large part to Michael Porter Jr. taking over for the Nets.
