Force play NFHS

[ajmc]

Consider, A's ball 4th & 10, on their own 10. A's punt is blocked (choose either side of the EZ) by B and caroms (either into the EZ where A recovers or through and out of the EZ)

The "force" is A's punt, the responsibility for where the play ends (either scenario) is A's, the result for either is a Safety, B's touching (by blocking the kick) is a non-factor.
