Ummmmm....no they don't. Defenders in short yardage have the same space to work with....half a yard...to build that momentum.....which is minimal.
Again...where are the supposed injuries?
The offense knows the snap count and gets to move first which is a big advantage to getting an initial push which is all that is needed when trying to get a yard. That is a big advantage for that small of a needed push.
I never said anything about injuries. That is not part of my argument at all.
that timing advantage exists on EVERY play, including the old fashioned Qb sneak. Again, half a yard....no time or space for 'momentum" to be built...and still FAR safer then virtually every other tackle in football where players are moving at far greater speeds.
The "injury risk" is a false flag IMO....I don't think it's real. If anything, it's safer then most plays.
SO here's the thing. If you wanna ban pushing in the back....I'm ok with that. But if they do that, it needs to be banned ALL THE TIME, EVERYWHERE, on offense AND DEFENSE. How often do we see gang tackles where one guy meets the runner and another defender starts pushing from behind the first defender, often three or four such players, who sometimes ALL end up piled on top of the runner.
