High school football has become more than local news and entered national prominence. Networks like ESPN and Fox Sports devote time and money to the production of high school football broadcasts just as they would for college football games.

With the profile of high school football being raised, so has the scouting of it and college recruiters spend as much time breaking down prospects as NFL teams do for college players. But which high schools are "football factories" in the sense that major college programs are such as LSU, Ohio State and USC? It should come as no surprise that these schools are often the ones given those TV slots as there is a good chance the players playing there now will be the same ones in the NFL in a few years.

With the help of Pro Football Reference, we’re able to see which high schools produce the most NFL players. The top 40 schools come from 11 different states with California the best represented with 13 schools. Texas and Florida each have seven schools to round out the top three states.

Here’s a look at the 40 high schools that have produced the most NFL players.
