Defender trying to take a charge starting to fall before contact

[SC Official]

Doing a trust fall backwards because you’re too scared to take the contact is not the same as ducking/bracing for the imminent charge.

Call a charge and have fun explaining to the offensive coach why you’re bailing out a defender who didn’t take the contact and put the offensive player in a vulnerable position. Call a block and it’s much easier to explain to the defender’s coach why you didn’t reward his guy. Plus that’s the expectation at the higher levels, and I disagree that there’s “no rules support” for calling it that way.
