Near impossible to tell what happened first in my opinion. I'm looking at 1:41 and there is no contact on the arm, nor is there any leg kick. by 1:42, there is both contact on the right arm (agree that it is marginal and doesn't deserve a call) and the right leg is now in front of the left. Both arm contact and leg movement seem to happen right at the change from 1:41 - 1:42.

What happened first aside, do you think the official was happy with this call after watching it? There are calls that I have made that might be technically correct, but that I wish in hindsight that I would have no-called. This seems like it would be one of those situations where the official in hindsight would have wished he had let this go as a no call.
