Metricating American football should be WAY down the list of priorities. Trying to do it early will just make folks mad. Once the US is nearly completely metricated, people will wonder about those yards and perhaps be willing to metricate football (its not like the rest of the world loves it and is just dying for a metric version). However, a 90 m field and 9 m of forward progress probably make more sense than blindly pretending yards are meters. The 90 m field fits existing stadiums and represents less than 1.6% change in total length, and progress for a 1st down. I am not convinced that a small change of the magnitude invalidates all statistics, I think they could be "adjusted." Certainly some other rules need to be revisited. I would number to the 40 m line, leaving a 10 m zone between 40's (Canadian football has two 50 yard lines). The meter line for kickoff (30 yard line) and taking possession (20 yard line) would have to be reconsidered, and the chainsmen would need a 9 m chain. Extra point attempts could be undertaken from the 2 m line. Pretending meters are yards is about a 9.4% change in total length, and progress for a first down. Besides not fitting most stadiums, I would argue that this would change the nature of the game and invalidate statistics far more than a 1.6% change. FIFA rounded the rules of the game in an apparently intelligent way. Important measurements were rounded to the nearest centimeter, and less important measurements were rounded further. I think a thoughtful approach would allow any game to be metricated, but not until the folks in charge of the rules or laws of the game are ready to undertake it.

However, only one addressed it to a new field length (90 m) standpoint. Changing field length to a full 100 m would require reconstruction of stadiums to provide space for a 100 m field. A 90 m field would fit most current stadiums; however that would require changing rules and void all previous statistics. Leaving American football fields size as is (100 yards plus end zones) and current rules would have the nostalgic but practical advantage for Fred Flintstone Units (FFU) in this case.

However, since teams have both an offense and defense, most would be equally affected. The likely result would be somewhat lower scoring.

The Penalty Area is specified at 16.5 Meters to accommodate the original dimension of 18 Yards. American Football, as Stanley Doore has mentioned does have a real problem with conversion. The concept of "first downs" would be altered by a ten-Meters requirement, and if the fields were enlarged to 100 Meters, with two 10 Meter end zones, there are almost no stadium floors that would accommocate these fields (more than 11M longer). In my opinion, American Football should keep the "Yard" as its measure and children can be instructed that it is a football measure, and left to die a slow and painless death as people get tired of explaining it in the far future. American Football is the only U.S. Sport I know that would suffer (statistically, and logistically) from SI adoption.

It is my understanding that soccer fields do not have a standard size. This makes it very easy to use metric dimensions entirely. Great! Not so with US football fields which have a standard size. Performance statistics are therefore based on the yard. Stadiums also are built with this in mind. Soccer fields could be standardized on rigid metric dimensions; however, wouldn't there be problems when trying to fit a standardized metric field size into various sized stadiums? Stan Doore ----- Original Message ----- From: Pat Naughtin To: U.S. Metric Association Sent: Saturday, September 26, 2009 4:33 AM Subject: [USMA:45897] Geelong wins national football championship Geelong wins national football championship So what, I hear you chorus. Who cares that Geelong has won the title as the Australian Rules football championship? However, this bragging is not the purpose of this email. The ground that the football game is played on is slightly variable in size but it has all of its markings in metres. See http://en.wikipedia.org/wiki/Laws_of_Australian_football This means that the sports commentators have continuously available references that they use to describe each game. The metric influence is continuous, especially the two arcs marked 50 metres from each goal. This has had the effect of making the descriptions wholly metric. I doubt that the transition to metric in Australian Rules Football would have happened so quickly without the constant metric reference lines on every ground built into the rules of the game itself. Perhaps there are some thoughts here for other metrication transitions! The game, today went for 100 minutes, but if you would like to get a flavor of the action there is a 10 minute sample at http://www.youtube.com/watch?v=xIOvSv9Q1Gk&feature=fvw Geelong are the only team to wear horizontal stripes of navy blue and white – watch for the Gary Ablett goal at 5:15.
