Exactly. I've always felt the whole weather home advantage topic is a crock. All NFL players have played and grew up in various areas of the country. To think that Miami or Buffalo players have an advantage because of their cities predominant weather conditions be it heat, humidity, cold, wind or snow to me is kinda funny.
Weather may effect play but it's not going to make Diggs feel any hotter than Hill or Tua any colder than Josh. Although it may be a different story in the trenches these are for the most part highly conditioned athletes who can tolerate inconvenient weather for 3 hours.
Of course it's JMHO.
