You see it every day on 49er forums -- Seattle trolls. You can identify them by their misuse of the word "dynasty", and their refusal to discuss history (they have none) other than to say that it's been 20 years since the Niners won a ring. They are also very good at distorting reality by saying that Seattle is better since "entering the NFC" or the past several years.
There is a book entitled NFL CENTURY which details the NFL in the 20th century during which time the 49ers won 5 Super Bowl rings, Seattle is only mentioned as an "expansion team". There is one paragraph that mentions Steve Largent.
Seattle has 17 winning seasons since 1976! The 49ers have 40 all told, including 16 straight seasons winning 10 games or more including 5 Super Bowls while Seattle was gathering dust. In fact, the Niners have a better record over the past 3 seasons and won the NFC West twice. They have one fluke that may not have happened if the official knew the rules on roughing the kicker and call it a dynasty.
Here are a few facts and fuel for the next time a Niner fan is faced with a DELUSIONAL. We'll be fair to Seattle and start the comparison in 1976, the year they joined the NFL. We'll disregard the fact that the 49ers had already played in a league championship game in 1949, that they had introduced the T-formation and shotgun to pro football prior to that time (not to mention the Million Dollar Backfield, Nomellini, St. Clair, etc.). Seattle's contribution? Adderall and loud speakers.
