WORST CASE SCENERIO! 
Alright, Let me review and correct your list
Detroit- that's a easy
WIN
Arizona- If Warner comes out sharp early, utilizing Edgerrin James, it could go either way, but more in favor for Arizona,
LOSS
NYG- Close game, but Giants defense will interven,
LOSS
Minnesota- Seahawks will get pounded on the ground because of their own ex-player on the other side, C. Taylor will have a field day plus Vikings DE's are good enough to stop S. Alexander,
LOSS
Kansas City- Chiefs defense will not be able to handle Alexander
WIN
Oakland- Defense is also weak,
WIN
St. Louis- That's easy,
Win
SF - That's easy,
WIN
GB - That's easy,
WIN
Denver - Denver will be solid,
LOSS
Arizona - Cardinals won't win two against the seahawks,
WIN
SF - Automatic
WIN
SD - close game but Seahawks edge out Tomlinson and company,
WIN
Tampa - Bucs don't have a good enough offense to beat the Seahawks
WIN
You are looking at 12-4 at best
