Actually up a little early today. Normally not home till close to 1am on Friday nights/Saturday Morning, but had quick game last night.  One of the teams ran a single wing and had a few long drives that ate us almost half of the game.  I am an umpire, so on a time out late in the game I was standing over the ball as the teams were lining up.  A DT told the LT that they play a weird offense.  LT said that they all hate it. I mentioned that is was real popular in the 30s and 40s.  He laughed and said there was a reason they stopped using it so long ago. 
Anytime I see a time running the single wing, I love it because I know it is going to be a short game.
