this happened to the team we played. i won't complain about the call, since we got the ball, but i want to know if that's actually a correct call

A1 inbounds. A2 dribbles, and almost bumps into the ref while trying to pass, and travels
the ref said "I'm part of the floor, so you just have to watch out for me"
is that how it is? if the ref gets in the way of the play?

He spoke the truth.

Same with OB, if Ref is OB and ball strike him/her the ball is OB.
