it was early in the 3rd. A was down 32 - 0. The QB did not appear to be intending to throw it backwards, he was just getting rid of it.
I know that doesn't change anything.
I was WH, I dropped a flag b/c from my angle it wasn't obvious it was backwards. My HL came over and said that was a backward pass. I waived off the flag 4th and 20 from the OOB spot.
Seems like a loophole to me.
