I'm not sure that's accurate, but I could be wrong. From what I've seen a few rungs down, though, it seems like most teams have 1-3 "good" players, and the rest are average (good compared to rec, but not stand-outs). The good players are usually fairly obvious, though, watching games, and they are not all on the top teams.
Now, it may be the case that the top teams are comprised of all such good players; I don't know, I don't observe that level. But I'd speculate, at least from what I've seen and been told (vis-a-vis D3 level interest in players) that a lot of the "good" players on lower level teams would be strong prospects for D2/D3/lower colleges. Currently, though, your options for visibility for such are club-hop to a top-tier team, or pay lots of money for ID camps.
It would be great if there were alternative options, even as an experiment in viability.
