Intentional means the player intended to commit the offence. I.e. intended to hit him in the head. Careless means the conduct breached the duty of care that players owe to one another (i.e. didn't intend to hit him in the head but nonetheless the act was dangerous).Pretty sure i never said he intended to hit him in the head, i said he executed the bump poorly. But the bump was intentional, people saying it wasn't are wrong, get it wrong this is the outcome.
