Lebron's layup from the Hawks game. Is this a travel I see this move used alot of fast breaks and it seems the refs never call it.

Mario picks the pass and throws down the fast break slam

LeBron auditioning to play TE showing off the hands before the fast break dunk

Klay Thompson picks up a T for a late pass to the ref

Is this a travel based on NBA rules Left foot is gather step, then 1-2 step after.
