What's wrong with my Seahawks?

Now I was born in Seattle, and I love my NFL team. I have been into football in the beggining of 8th grade(now in 9th) so Im a amateur into football. But I have learned a lot though. But not enough. I can't watch the seahawks play because I live in VA and I only get east coast football. But I have watched the seahawks play on YouTube or tv when they show the high lights. I'm really getting fustrated since they have lost to TAMPA BAY! We beat the 49ers but not the texans or tampa bay. What are my seahawks doing wrong? I have noticed that Helbeck is some what of a slow runner, and the seahawks do have a weak offense line. Other than that, what are the seahawks doing wrong?
