We're all getting better at calling travel violations or at least we should be trying to get better at it still.
Had a C level game last night and this kid throws the Euro step on a fast break. Caught me completely off guard and I rewarded him with a travel. I was upset because I thought I cut out most of my whistles where it just "looks" funny.
But as others have said, identify the pivot foot and traveling becomes a much easier call.
