Okay kiddo, so the Pittsburgh Steelers is a team of grown-ups who play a game called football. They're from the city of Pittsburgh, which is in a state called Pennsylvania in the United States.
The Steelers have a big stadium with lots of seats where people can come and watch them play. There are two teams playing at the same time, and they try to score points by carrying or throwing a ball to the other team's end of the field.
The Steelers have been playing for a really long time – since the 1930s! They're really good too, and they've won lots of games and lots of trophies over the years.
They have some really cool players, like a big strong guy named Ben Roethlisberger who throws the ball really far, and a fast runner named James Conner. They also have some really good defenders who try to stop the other team from scoring.
The Steelers have a lot of fans who love to cheer for them and wear their colors – black and gold. It's a really fun team to watch and root for!
