How does this relate? What does it mean, even?

I also couldn't be sure that A1 wasn't trying to leave a high bounce for a trailer.

I learned a long time ago to try to call what I can explain.

If you don't call this a violation based on the idea that it might have been a bounce pass to a guy trailing the play, trailing 40 feet behind the play, I'd like to be there to hear that explanation.
