Are the Pittsburgh Steelers in the AFC?
I know absolutely nothing about sports.  Is this football?
Yep they are an NFL team out of Pittsburgh that has won the Super Bowl 6 times.
Well, I've watched the Super Bowl commercials!  
You and 114.4 million other viewers as of 2015!
Well that's my extent of paying attention to sports.  But everyone has heard of the Super Bowl.
Much more popular here in the USA than Soccer. The United States Soccer Federation has an uphill battle compared to the rest of the world.
Yes but there was a big game in Atlanta recently that appeared to be well attended.
That and the Women's World Cup Soccer team here in the US. They've really been killing it lately.
I have a feeling it will be competing with baseball pretty soon.
