Oh! Hail Mary! (or OHM, Ohm's Law)

 

Silly Explanation of Acronym: OHM (Oh! Hail Mary!) (1) Some background -December 28, 1975. NFC Divisional Championship Game between Dallas Cowboys and Minnesota Vikings. "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 fourth 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) pass.
