As a Cavs fan I feel obligated to mention that this was a travel since his right foot was his pivot foot and that is what he dragged across the key.
But, travels get missed all the time, and being a fan of the team with Lebron, I can't ever complain about a travel not being called.
All that being said, I absolutely loved that move as a basketball fan.
I have no idea what you're talking about. I don't see a travel anywhere.
I don't know the exact rule on it, but i believe MAC is referring to the fact that he slides about a foot on the floor before coming to a stop, with both feet clearly in motion without a dribble.
Not sure what the rule on that is, players normally aren't going so fast that they can skid by coming to a stop

My second thought, after closing my jaw, was in fact that it's a travel.
But, as other's have pointed out, considering the murder that players are allowed to get away with, I'm very glad the officials didn't ruin that awesome move by calling a travel.
Side note, what is the rule on that? can you come to a stop via sliding?
I guess it comes down to if your pivot foot is established once your slide ends or when you plant? i guess?
Or at least that's my (probably wrong) thinking, that this may not be a travel because his pivot isn't established until he comes to a stop from the slide?
Regardless, just an absolutely brilliant move.
