Last Play of Regulation…

I watched Super Bowl LI on February 5, 2017.  I have no problem with the teams playing. Having played football into college; I have a problem with the play call on the last play in regulation.250px-post-pisarcik_qb_kneel_formation-svg

Fine you have a tied game and seconds left until overtime begins.  The Patriots line up in a kneel down formation, OK fine.  It is a regular play, but just like unwritten rules in baseball, this has the unwritten understanding in football:  If the defensive line fires off into the offensive players on the other side, then the defense is making an egregious assault on the norms of the game.  fine here, unwitten rule, offense not fined, here, Until…

The Patriots line up and run the ball out of this formation for an inconsequential gain at the end of regulation.  Every time Belichick and the Patriots line up in Kneel Down formation, there will be no more line man standing up and shaking hands.  There will be defensive linemen firing off and nailing the offensive linemen for one last time.  Because of this stupid call.

The NFL and the Ideal Gas Law – Part 2

CaptureI posted a while back about this topic.  But the official report came out last week and punishment followed shortly after, so I thought I would add some more of my thoughts.

There were two things I found interesting from the Well’s Report recently released.  In the report there is the evaluation performed by Exponent.  Where they were tasked with evaluating the scientific principles at play that may have accounted for the pressure drops observed on January 18, 2015. I have concerns that deal with the initial conditions of the footballs – What was the actual initial pressure?  and What was the temperature of the gas at the time of the initial measurement?

  • Two gauges were used on game day (logo & non-logo) to read pressures.  The gauges had readings that differed between 0.35 psi and 0.75 psi.
    • I would have tried to reconcile the instruments to some standard (i.e. to adjust the measured readings to a reference), and tried to ascertain which gauge was used and when during the day in question, January 18, 2015.
      • For example, the logo (higher reading) gauge could have been used pre-game to give a measurement that could differ up to 0.75 psi, meaning the gauge could read 12.5 psi, while the non-logo gauge would read it as 11.75 psi. Now if the non-logo gauge would have been used at half-time, then the pressure drop due to temperature along with the initial discrepancy would need a drop to the 10.5 psi measured (0.75 psi from device difference and 1.25 psi from temperature change).  Meaning the initial temperature of the gas in the ball would only need to be 73.1 degrees Fahrenheit.

Duplicate Numbers

I must be out of touch.  I was unaware that players on the same team do not need to have unique numbers on their jerseys.  I thought it was a given that for any team sport with jersey numbers, the number you wore would be the only one for that team.  (NCAA rules to follow after I show some pictures from the Citrus Bowl)  This bothered me, I spent a quarter looking for the defensive number 7s that I knew I saw.  Why do you need a full roster of more than 99 players (105 players is the NCAA cap)?    Eleven players on the field at a time.  If you want to dress out your red-shirts for whatever reason, fine.  But come on… Continue reading ‘Duplicate Numbers’
