In fairness as a neutral I hate that Finucane tackle.
I don't get how we can (rightly IMO) penalise that if he's just thrown the pass but not if he holds it. Like the chat in a (Dragons?) match day thread a week or two ago, Finucane isn't making any attempt at a tackle. He's just come out like a missile looking to smash into Crichton however he can and he's real lucky the swing arm misses.
If we're going to penalising incidental high tackles, and it we've banned shoulder charges, then we should also be looking to rub out careless tekkers like that IMO. And there will always be thickskulls who say "hurr durr penalty for tackling too hard" but I defy anyone to call a hit like that a tackle.
You can rattle blokes with a perfectly fine, hard tackle. It just strikes me as unnecessary to act like a human cannonball
