Someone on Twitter pointed out that there is some case law that 3rd degree can’t be used when the defendant had a specific target. If that’s the case then 2nd may be more appropriate after all. But then again, an (admittedly quick) look at the caselaw shows that they’re really inconsistent about it.

You're very welcome, glad it's helpful.

There are statements that they had been trying to get him in the car after he was handcuffed and were unable to due to his resistance, which led to the scuffle on the ground. I also read that one of the officers got a hobble restraint out but someone, maybe Chauvin? opted to continue with physical restraint rather than use it.
