- Silly Explanation of Acronym: OHM (Oh!
Hail Mary!) (1) Some background -December 28, 1975. NFC
Divisional Championship Game between Dallas Cowboys
(sorry for Redskins fan. But remember I am from Texas. I
am not much of football fan, though.). "With less
than two minutes to play and trailing 14-10 the Cowboys
took over possession of the ball on their own 9-yard
line. QB Roger Staubach led the Cowboys attack by
hitting WR Drew Pearson on five different passes
including a clutch 22-yard forth down conversion at the
50-yard line. On second down, and only 36 seconds
remaining, QB Roger Staubach threw a desperation pass to
WR Pearson who was being covered by CB Nate Wright.
The pass was caught by Pearson on the five-yard line, and
he strolled into the endzone for the winning
touchdown. QB Roger Staubach, in a post-game
interview said "It was a Hail Mary pass."
A moniker that would forever stick describing this
particular catch and created a new lexicon for all
similar pass plays to follow. (excerpts from www.ffbookmarks.com). All in all, Hail Mary pass is a forward pass
made in desperation, with only a very small chance of
success. The typical Hail Mary is a very long forward
pass thrown at or near the end of a half where there is
no realistic possibility for any other play to work,
though the most famous were thrown at the end of a game.
(2) OHM's law is about V=IR. But most of time, we do
forget or does not have clear idea what V is. The V is
voltage across the R. This simple thing is somehow very
difficult to be registered to students. So the ball
thrown from QB is the V, and the WR who runs across the
field is I, and the CB/FB are the resistance R. Remember,
V in Ohm's law is voltage across the R. In other words,
the potential difference between one end and the other
end. To do that in one shot, you need Oh! Hail Mary (OHM)
