My two friends who went to the game at Barclays texted me. They said it was like 75/25 Nets-Celtics fans BUT in the general area where they were sitting, the people there were wearing casual clothes and are KNICKS FANS lol. Not even Nets fans.
There might not even be many real Nets fans at the games
Also said there was a big "Lets go Celtics" chant at the end which we all heard and they took part in. Said there was even some attempts at a "Kyrie sucks" chant throughout but those got bogged down lol.
They had fun!
