I think one huge positive for the growth of the national team pool has been the rise of USL and other lower leagues in recent years. I can't speak for every area, but here in Genesee County MI (Flint) basically every youth club has an affiliation with a "pro" team like Flint City Bucks, Detroit City, Ann Arbor AFC etc. Its a small step but I think we should start seeing it have a larger impact on our talent pool in the coming years.
