Pennsylvania has two professional football teams - the Philadelphia Eagles and Pittsburgh Steelers. There are also dozens of college teams, most notably Penn State and University of Pennsylvania. There are also many, many high school football teams.
a lot how many high schools are there?
Check out the link below for National Federation of State High School Associations. The updates are done regularly so depending on when you are looking for the answer to this question, this is the agency to go to! I don't know that anyone knows the answer to that. Just about every high school in the U.S. plays basketball. So I would say there are several thousand high schools that play basketball.
In Canadian football, while only 12* players are playing on the field at once, teams need more than just 12* players. They must have an offensive and defensive team. Most high school football teams have 1st, 2nd, and 3rd string players, so thirty to forty players is a reasonable number. * only 11 in American football
there are many but some of the most common ones are football, baseball, basketball, softball, volleyball, and soccer.
