There is a bit of confusion for every MLS fan outside of Seattle.

Does having the largest average attendance in a stadium that was built for NFL football make your fans "the best?"

There's no doubt that the vocal sea of green has created a exciting spectacle of viewing in the high-definition sports age, and Major League Soccer could not be more thrilled.
