The team, who were nearly too big for the subway vehicle, were squishing together for the ride.
Still, it's startling to see a LeBron James-led team being projected to miss the playoffs after seven straight Finals appearances.
LeBron James, Dwayne Wade and the rest of the Cleveland Cavaliers squad choose the six-minute train ride back to their hotel following their shoot around ahead of tonight's game with the Knicks at Madison Square Garden. The players made some new friends - like this guy who clearly had no idea LeBron was sitting next to him.
"Can you not", the fan said before moving his seat.
According to James, the video marked the first time he had ever ridden the subway.

I don't want to think it's the game of life but I'm convinced that, with the help of the fans, we will do it. Before the 3-0 defeat in Madrid, Italy was unbeaten in 50 World Cup or Euro qualifying games.
"Trying to be like real citizens man", Smith said to the camera.
James said Monday was his first time riding the subway in NY.
Calderon, who was spotted in the gym early on Monday morning, had his camera rolling as members of the Cavs patiently waited for their train to arrive at the station. "As long as I'm getting on the right (expletive) train that's all I care about", he said.
The MTA responded to James' video thanking him for riding the subway while also reminding him NY is a Knicks city.
Ironically enough, the Knicks will now battle James and the Cavaliers on Monday evening at 7:30 p.m.
