SAN ANTONIO — Victor Wembanyama’s flagrant foul represents a good starting point. Wemby getting egged as he returned to the Spurs’ team hotel represents a good ending point.

In between, how did the Knicks pull off the comeback of all comebacks? How did the Spurs produce the collapse of all collapses?

The Knicks’ miraculous 107-106 Game 4 win over the Spurs on Wednesday night at Madison Square Garden — which gave them a 3-1 Finals lead heading back to the Frost Bank Center — was a story of both the Knicks elevating and the Spurs crumbling.

One does not happen without the other.
