I get why it was paid too BUT the issue I have is, why is this a free in the 1st place? We know why a push in the back in a marking contest is a free, because it gives the player behind an unfair advantage, but what is the purpose of this free for PITB when tackling? Protects from injury? Not sure, how many players have been injured from this action? I'd guess a very very low %, so why is this even a free? We should be rewarding good tackling like that, not penalising it.
I've mentioned this on here before, so its not isolated to the Balta tackle, IMO it just seems to go against the spirit of the game to pay a free for that type of action.
