Seattle Seahawks fans yell during the first half of an NFL football game between the Seattle Seahawks and the San Francisco 49ers at CenturyLink Field, Sunday, Sept. 15, 2013, in Seattle. Fans were attempting to set a Guinness World Record for crowd noise at an athletic event during the game. / AP These aren’t games. Never were, never less so than now. That the Chargers play the Seattle Seahawks on Friday night and then again in the second week of the regular season is of little consequence to the participants. It doesn’t change anything. Its significance is in the NFL implicitly acknowledging that the preseason does not consist of games.
