Pardon me small human, I wish to be on top of this pile of men.
This is actually the correct and sporting thing for the blue player to do in this situation. The guy he tosses should have been trying to roll away in order to rejoin the ruck from his team’s side.
The less sporting (but still mostly allowable) thing to do would be to use the cleats to push him away.
This is Rugby. Now get the fuck out of the way.
