Ben Simmons wasn't even the worst thing about the Brooklyn Nets' opening-day home arena debacle against New Orleans.

Local rapper Fivio Foreign played the halftime show and many who watched it declared it the worst performance they'd ever seen.

TMZ caught up with Fivio and asked him what went so horribly wrong.  Here's what he said.

“What it is is that’s not really my production team. That was a different team I don’t use all the time. I did the soundcheck, sh*t was good at soundcheck. I just gotta use my production team from now on," Fivio explained.

According to Fivio, it was the Barclays Center's production team.

Whatever it was, he wants a do-over.

"I don't want to let Brooklyn down.  I have to redo that sh*t," he said.
