Knicks rookie Frank Ntilikina’s fourth-quarter benching was more the Frenchman’s call than the coach’s. Feeling flu-like symptoms, Ntilikina had his worst game as a Knick, committing four turnovers with zero points and one assist in 11 minutes and sitting for the fourth quarter. Jeff Hornacek said Ntilikina told him he wasn’t helping the team, prompting the Knicks coach to bench him and allow veteran Ramon Sessions to play the fourth period. “Frank’s under the weather,’’ Hornacek said after the Knicks’ 107-85 victory Monday. “He’s been fighting it two, three days now. he just didn’t have it tonight. He was fine with it. He actually said, ‘I’m not helping the team now.’ Frank’s a smart player. He realized he didn’t have enough energy. He sacrificed. He could’ve gone back in there and still played but it gave Ramon a chance.” Ntilikina, who didn’t deny that version of events, said he got sick in Toronto and is on medication.
