Took 7 months for me to ask??

It makes no difference whether it was intentional or not

Actually, it DOES matter, though I'm not necessarily disagreeing with your opinion here as its based on the OP play. On that one, obviously, you'd have to see it, but the key question is: did the offense gain an advantage? Yes = flag; no = pass on it.

However, if it is clearly unintentional you are more likely than not to pass on the call. Here's an example that happened in one of my games last year: sweep or pass play to the flat, offensive lineman out there blocking and ends up face down on the ground (no foul involved). Right behind him is his teammate who's engaged with a defender and they both trip over the guy on the ground, who might have been in the process of getting up (I didn't actually see this). Chop block? No way, even though by definition, it fits (and the fact that the coach is yelling for it).

You apply advantage/disadvantage to a chop block call?
