The words from “The Letter” came back to haunt LeBron James and the Cavaliers in this game: a game that no one in Northeast Ohio thought the Cavs could lose. LeBron looked nervous. David Blatt looked overwhelmed. And the Cavs looked like they’d bought stock in the seriously ill-conceived “big three” narrative. Honestly, there could have been about a dozen more subtitles to this recap. Examples include: “Andrew Wiggins would have blocked that shot,” “LeBron has terrible games too,” “Defense matters,” “That crowd sucked,” “Go back to Hollywood, Biebs,” or “Oh that’s right, Carmelo Anthony’s pretty good.” Ultimately though, the Knicks just played with more energy, intelligence, and focus. The energy that had infused the entirety of the city of Cleveland throughout the day seemed to drain the Cavs instead of fuel them.
