I already compared them - the reason for the difference in gradings was the result. Guelfi went off the ground (and hospital for checks) AND reported neck soreness which caused the grading to be high instead of body and medium instead of low impact. Pretty clear - he chose to push him into a fence - he takes the responsibility for the end result. This could have been avoided if he did not make the secondary pushing action OR tackled him instead.
So a 196cm 100kg chb bumps a lighter opponent shoulder under shoulder with pace and that didnt propel the player into the fence?
It was this so called second pushing action that pushed him towards the fence?
What exactly was the time difference between the shoulder impact on body and this secondary action you keep bleeting about?
You run through and bump a player they go flying. Your arms follow through after the shoukder impact. Thats physics and football. Especially big elite players bumping smaller players.
You read like you've never played or layed a decent bump in your life.
And whats your motive to grinding this axe? You seem very focused standing on your soap box waving your pitch fork around.
