IIRC, no longer having my old books, at one point a tackle from behind was explicitly a foul if contact was made before the ball was played. That was before CREF was invented. While not formally in the Laws, I think it remains a real factor in determining CREF—a lesser degree of contact is careless if it takes place before the ball is played than after the ball was played. The player’s “but I got ball,” is an overstatement as they mean “as long as I touched the ball at some point it can’t be a foul no matter what else I did.” But that doesn’t mean getting the ball is irrelevant in considering whether the play was careless or reckless. (I’m failing to picture a scenario where it would change excessive force, but perhaps there is one.)
