But I am sure I won't be seing any reliable links to support your hyperbole.

While the South may produce more athletes per capita, the West Coast makes up for it in population. For example, San Francisco alone produces more NFL players than Atlanta (but you're right, nowhere outside of South Central LA produces athletes on the West Coast):

Also, the west coast is the second best region in the country for producing NFL players, and based on current trends, the West Coast will be number one in the not so distant future:

When compared to the Big 12, the Pac footprint produces nearly 25 percent more NFL players than the Big 12 footprint:

But the advantage that the Pac has over everyone else (including the SEC) is that it shares its footpring with no one. Unlike the Big 12, the SEC, and the ACC, it has a complete monopoly on its region when it comes to recruiting athletes.
