This is what the playoffs are all about. The Nets and Sixers are developing a fiery rivalry.

It was started by Dudley, who said Sixers All-Star Ben Simmons was an average player in the half-court. In Game 3, Simmons put up 31 points and 9 assists. He also waved at Dudley after the Nets swingman airballed a 3-pointer.

The Nets are playing like a desperate team in Game 4. If they lose, they'll be down 3-1 in the series. Brooklyn is trying to get back in the series and Dudley was looking out for his young center in Allen, who got elbowed by Embiid in Game 1 as well.

The refs will be paying close attention to this series now. Fights are never a good look for the league, even though fans love them. Let's see what happens next in this exciting first round series between the underdog Nets and Sixers.
