I can speak a little about Herndon.
For varying reasons, several of the seniors decided not to return, as did one promising sophomore. Just a different time for the program, I think; partly, its a change in the demographics of the area (fewer players try out), part of it is that there are more competing sport choices, and part of it is that there is a certain amount of upperclassman attrition that just seems to hang over the program.
On the more positive side, it will give the underclassmen opportunities to step up and test themselves. Juniors Tyler Reif (lhp/of), and Matt Smith (catcher) should have productive years. Senior Dylan Garten (who can basically play anywhere they need him) has committed to Shepard University.
