^^^^^^^^^ yup, there's an angle that clearly shows him take a few steps with the normal amount of knee-lift but then just as he goes into contact the leading knee comes up significantly higher & collects the tackler. You could argue about the five weeks, but not that it wasn't deliberate.
Said the same thing on another thread. Once you slow the video down (YouTube, 25% speed), he clear flings that knee into the tackle.
You see ball-carriers also swinging forearms into heads in a similar deflection tactic, and I'm not sure that's all that much better. In the NRL, one of the counter-arguments for banning the shoulder charge is that ball carriers can basically do the same thing. Ben Te'o has done it more than once at Leinster since he arrived.
And as I type that, the Georgian hooker does exactly that, smashing his forearm into the Namibian #23 while carrying the ball, and he's just been given a yellow card for it.
Sidenote, because there's no thread: The Namibians are trying to wrestle with the Georgians too much. They can't wrestle the Georgians. No one can, except maybe the Russians; the Georgians are nearly as good at wrestling as the Russians, and they're better at rugby. Don't wrestle the Georgians.
