The party following the New York Knicks’ first NBA title in 53 years lasted all summer.

On Tuesday night, the Knicks get back to business —?after one more celebratory flourish honoring a championship that was generations in the making.

The Knicks will raise their championship banner Tuesday night in Madison Square Garden before they open their title defense against the longtime rival Philadelphia 76ers, who added LeBron James and Jaylen Brown in hopes of dethroning New York.
