Possibly the worse take I've seen on this. Congrats.
If the tackles were 'stronger' they'd probably take Ginnivan's head off. Also most of these high free kicks are not when he's got his head over the ball. He gets the ball and then runs around for a second and then performs his technique. Good for him, he get's the free kick and goal, but it needs to be stamped out.
By your logic a player could pick the ball up and just straight headbutt someone and it should be a high free kick.
I said you cannot duck your head, but I have no problem shrugging, dropping your knees, pushing the tackle high if you can against the weak tackler.
I take it you have been watching footy for not that long, you think the player should stand up rigid and let the tackler tackle him?
You want it stamped out, then tackle lower. Just unbelievable the coaches are not training their players to tackle lower.
