Knicks embarrassed in season-opening beatdown to reigning champion Celtics

BOSTON — The Celtics feasted on the Knicks after their coronation ceremony.Touted as the top threat to Boston in the East, New York put up the resistance of a wet paper bag in Tuesday’s ghastly and concerning season-opening defeat in Beantown, 132-109.It was a mess right away for the Knicks, who trotted out their expensive and star-studded lineup and trailed by as many as 21 in the first quarter.Tom Thibodeau’s squad never recovered.It folded, in fact, allowing the deficit to hit 35 in the second half while serving as compliant guests to a Boston “Three” Party.The Celtics knocked down 29 from beyond the arc, tying the NBA record.

But Bridges was also barbecued on defense by Jayson Tatum, who dropped 37 points in 30 minutes — including 8 of 11 on 3-pointers.The Knicks were outscored by 33 points with Bridges on the court.

The Celtics, who received their championship rings before tip-off, had clear and uncontested looks at the rim.It would’ve been hard to imagine a worse debut for Leon Rose’s construction.Jalen Brunson (22 points, 9-for-14 shooting) and...
