No. You've got the wrong idea. I am always, 100% of the time, a San Diego Chargers fan. As long as they're on the air wherever I'm at, or if I'm in San Diego, I will watch the San Diego Chargers play... and I will root like a madman with rabies for them.
Since I started paying close attention to the Chargers around 1986 or 1987, I've endured an 8-1 season turning into an 8-7 season (1987), four straight losing seasons from 1988 to 1991, eight straight .500 or worse seasons from 1996 to 2003 (only two of which were 8-8 finishes), and the inability to win a first playoff game in 2004 and 2006.
But I've always remained a fan.
As far as the rest of the NFL, however, I've recently noticed something: if the Chargers are doing poorly, I don't give a small shit about the rest of the league. If the Chargers are doing well (or, as now, are fighting for a playoff spot), I'll watch damn near every NFL game I have access to.
So, yes, I admit it: I'm a fair-weather NFL fan... but an all-weather Chargers fan.
I just watched Drew Brees tie Rich Gannon's NFL record for the most 300-yard passing games in a season (10), become only the second quarterback in NFL history to pass for 5000 yards, and fall 16 or 17 yards short of breaking Dan Marino's NFL record of the most passing yards in a single season.
While I can dig Philip Rivers, I really wish Drew Brees was still a Charger.
Tonight the Chargers (7-8) play the Denver Broncos (8-7). If the Chargers win, they'll win the AFC West and are in the playoffs. If they lose, well, it'll be another disappointing season... and Norv Turner will have to go.
Here's hoping for the best.
