I think you hit the nail on the head when you said funding. Here in PA high school programs get major dollars. The smallest school districts have football stadiums that probably rival the best programs in CT... and youth football football starts at 4 years of age, 5 days a week. The youth organizations get their playbooks from the head coach of the local high school. We DID NOT have this in CT growing up. Soccer maybe the #1 sport by the number of participants, but it's not taken anywhere near as seriously by most of the participants as youth football is here. It probably explains the number of PA kids as well. And this is in Eastern PA... an area that I think is actually under-recruited.
I actually think one of the advantages UConn has is that it's smack dab in the middle of some decent football playing areas that are overlooked by the majority of college programs. Eastern PA, the New York suburbs, upstate NY, and New England. It just takes a lot of work to find those kids... they aren't scouted from 5th grade up. They don't have access to the regional camps that get the most attention... but I think Edsall proved they were there. Fast is fast, no matter what state you come from.
