Muff Kick

[Legacy Zebra]

OK, so real quick: change the play a little to where the punt is from deep in A's territory. Everything happens like in the OP, except the ball isn't recovered. Now, the muff causes the ball to go back into A's end zone where it goes out of bounds.

Ruling?

In NCAA, it’s a safety. The impetus is still A’s punt since muffing a loose ball does not change responsibility unless the ball was at rest.
