PHILADELPHIA — Jalen Brunson, Josh Hart and the New York Knicks are back in the Eastern Conference finals, tying the NBA postseason record with 25 3-pointers in front of a raucous crowd rooting for the road team and rolling past the Philadelphia 76ers 144-114 on Sunday to sweep the second-round series.Deuce McBride started in place of the injured OG Anunoby and hit seven 3-pointers, going 4 for 4 in the first quarter when the Knicks had another record with 11, and scored 25 points. Brunson had 22 points and Hart and Karl-Anthony Towns each scored 17 in the Knicks’ latest lopsided playoff victory.The Knicks’ 19.4 point-per-game margin of victory is the largest through two rounds since the playoffs went to 16 teams in 1984.“It’s just us being very locked in to the moment,” Towns said.The Knicks advanced to the East finals for the second straight season and will play the winner of the Cleveland-Detroit series. The Pistons lead 2-1.The Knicks last season reached the conference finals for the first time in 25 years before losing to Indiana.
