Except that's not what happened. He wasn't picked up and he wasn't already going down. Luke was fighting through the contact and one of the defenders took out his legs, which is what he's supposed to do.I don’t know. Anytime you pick someone up who is already going down and flip them onto their head/neck, you are intending to do something more than tackle them….
I think it's notable that our coach specifically singed out the refs after this game, with specific examples, and as far as I am aware did not mention this play. If what you claim happened actually happened, this would be Exhibit A in any complaint about the refs. Instead he talked about the targeting call against Scott and uncalled the late hit against Luke.
But if you want to explain what penalty the refs should have called, and cite to the language in the rule book that supports the penalty, I am always open to changing my opinion.
