Halftime Report: Knicks 54, Mavs 49

The Knicks are in Dallas, trying to start the season 9-1 for the fourth time in franchise history.

So far, they’re off to a decent start, up five at halftime.

Here are a few observations from the first half:

CARMELO COOLING OFF? Carmelo Anthony took the court on Wednesday as one of the hottest players in the NBA. But he had a tough time in the first half against Shawn Marion and the Mavs.

Anthony is 1-for-6 in the first two quarters with four points, but the Knicks are still up thanks in part to solid play from Tyson Chandler (12 points, six rebounds) and Ray Felton (10 points, four assists).

KIDD-ING ME? Much was made of the reaction Jason Kidd would get in his first game in Dallas after signing with the Knicks. The ex-Mav received some warm cheers during intros and then showed Dallas fans why they were upset that he left.

Kidd had nine points, four steals, three assists and two rebounds in the first half. Kidd knocked down three 3-pointers as the Knicks hit nine of 19 attempts from beyond the arc in the first two quarters.

EXTRA O.J.: O.J. Mayo torched the Knicks for five 3s in the first half on Nov. 9 at the Garden. But the Knicks slowed Mayo and the Mavs in the second half to pull out the win. So far on Wednesday, the Mavs are following a similar script, as Mayo has come out and exploded for 13 points on 6-for-9 shooting in the first half. Vince Carter has come off the bench to knock down three 3-pointers to help Dallas keep pace.

Dallas has forced seven Knicks turnovers. If the Knicks match that number in the second half, they’d finish with four more than their season average of 10, the lowest per-game number in the NBA.
