Anyone remember the experiment the NFL had many years ago with regular season football games broadcast entirely without commentators? The video had all the normal 'heads-up' type information on the status of the game: score, down, distance, etc, etc, but there was no Bob Trumpy to tell you what it all meant. Didn't last long, and local games would always have local analysts... or we would just listen to Cope on the radio.
It came to mind because I was thinking that I will experiment here and put this up entirely without comment on it. The data behind this figure is online here
, but this is the trend in total weekly wagering at the two local casinos since the beginning of 2009. What is there to say? or not say.
