Name the loss that you think had the biggest impact.
The way I see the next 2 weeks, it looks to me like we realistically lose a head-to-head with the Chargers for the 6th seed based on remaining schedules. So one could say that the loss to the Chargers was the biggest. After all, McDermott decided to start Peterman over Taylor in that game and he shat the bed.
But to me, the loss to the Jets on Thursday Night Football was the one. We were so unprepared for that game - it looked like at 5-2 we believed that we'd win if we just showed up. And that began our 3-straight-blowout-loss downfall. But the other 2 were against teams that ended up in the playoffs (in this scenario) and were at least semi-expected. I do believe that we SHOULD have beaten the Jets that night, and Tyrod DID start that one.
The other huge loss to directly cause us to miss the playoffs in this scenario was Tennessee losing to San Fran on that last second field goal last Sunday. We would win a 3-way tie at 9-7 including Tennessee.
I'm not giving up on this year - stranger things have happened than San Diego losing to the Jets or Oakland, or Tennessee beating the Rams or Jags, or even us beating New England.
