Seahawks were 1-7 on the road last year, this year they are 0-2. What are the reasons for poor performance away from home?
This one is a touchy subject for most Seattle fans, but the problem for the last several seasons has been that the Seahawks have not been a good team. By 2008, the players who took the team to the Super Bowl back in '05 were mostly gone or old and ineffective, and (now ex-)general manager Tim Ruskell failed to re-stock the team with talent. Really what people should be asking isn't why the team lost so many games on the road, but how did they manage to win so many games at home? (Answer: they've got one of the best home field advantages in the NFL.)
There's a bigger problem at work here, though, and that's forcing West Coast teams to play morning games on the East Coast. I know jet lag doesn't sound like much of a factor, but the level of play in the NFL is so even anymore that any little advantage can be enough to swing a game. If road games to the East Coast were all moved to afternoon time slots, that would go a long way toward alleviating the problem, but none of the West Coast teams seem to have enough clout with the league to force through a change in that regard.
That said, back in 1983 the Seahawks beat the Dolphins in Miami to advance to the AFC Championship game after getting just a few hours' worth of sleep due to a delayed flight, so who knows?
