This incident has highlighted a number of things for me. Fact is, Butt hurt Dragons fans are the biggest sooks in Rugby League and whatever they came up with was destined to be further cultivated by the lol@souths brigade. The media aren't blameless in this hysteria either.
It's also shown how few of the people in this thread have actually played Rugby League. If they had, they'd know how laughable half of what they've said here is.
When you make a shoulder charge at pace you are trying to smash your opponent and you generally aren't watching your target at point of contact. If your target changes direction at the last moment, even minutely, it's impossible to adjust. It's why so many shoulder charges actually miss completely. Look at Young's body position in that shot. Farrell has dragged him down and to the left at the last minute. It's only about 6 inches either way but when Inglis is already taller, that's all it's taken and still, first contact is forearm with the chest.
If Farrell isn't involved, it's just a good solid hit. Contact with the head was not the intention and Inglis had no time to adjust. Same as Kasiano last week and should be the same result.
