How long until nearly live advanced football metrics exist? I would have to guess that to a large extent they are being processed at the team level - someone on each staff inputting data from the current game to existing sets that might predict which way a run will called or when a linebacker blitzes from the weak side. This week the Sunday Night Football broadcast said that Peyton Manning's completion percentage to one of his wide receivers was one of the worst in the league between a quarterback and receiver but why can't that be live and why can't there be more?
Video games have the ability to put circles, numbers, names and other icons below a player's location on the field and I don't see why professional football can't do the same. It would be amazing to see Manning line up in a third and long situation and see the percentage of times he throws to each player in third down situations of nine yards and longer. Even better, once this level of information is available, the viewing experience though a television - or more likely screen with information fed through a computer - would be user based and the statistics displayed could vary.
While on the idea of technological advances in football, I would like to see a chip put in each ball to determine it's speed, rotations, location on the field and vertical and horizontal positions. These data, linked with the official time would end all replay delay as officials could use the rotation per second of a pass, catch and then possible fumble. The league could even institute a standard rotation range allowed and anything over that level would be ruled a loss of possession by the carrier.
The league is too valuable to remain without innovation and my guess is that a more interactive experience - through this data or something else - isn't too far of an experience. Until then we're stuck with the basics statistical measures, 90% of the time.
