Meh, you're trolling now. My argument is that Pocock's knee isn't obviously deliberate. Posting a picture of an MMA fight is just the most obvious folderol.
A. You said knee strikes were okay in rugby, I didn't;
B.) Didn't post it, linked to it;
C.) I'm not clear myself if it's obvious or deliberate or not. But don't agree that any sort of striking is fine, whether it's incidental or not. If Tipuric freed his leg from Pocock's grasp by sending a knee to his chest as opposed to grabbing him, or putting the knee to the hip, or on the ground, or just about any other place other than the chest, I really doubt people would be saying there was nothing in it.
He's not even been cited yet, so it's really not for anyone to say. I'm just disagreeing with the "knees strikes are okay" sentiment. If they were, Tuilagi wouldn't have gotten a ban.
