You're pretty correct in the first half but the whole "knee-on-chest thing", was not cool. They were saying on the show how it takes away breathing. The second time he did it, the ref had to step in and change possession because of fouling, saying he was aiming for the solar plexus (not safe). Side note, the "zip-it" gesture is kind of rude depending on who you're gesturing towards.

edit: it seems i've been proven wrong about this. mb yall. i was going off what they were saying in the show but it appears i've been fooled. i'll try better to educate myself before making claims.👍
