If it turns out Jalen Brunson is badly injured, there’s not much more to say than: The Knicks are cooked.

Good job, good effort, fun season, let’s reconvene in September.

Brunson, the Knicks’ All-Star guard and talisman, exited in the first minute Sunday night in Cleveland due to a left knee injury and did not return.

He took a knee-to-knee knock while going up for a free-throw-line jumper on the Knicks’ first possession, grimaced in mid-air and collapsed in a heap. He tried to limp off, but his foot looked off-kilter and he needed help leaving the floor.
