Did a quick twitter search and Davis and Jest, who both are active on Twitter, both still have University of Akron in their bios. Holley does at well, but he hasn't tweeted since signing day. Nelley doesn't seem to have an account, so not sure there.
With such a tiny recruiting class, you'd hope that everybody qualified. But on the bright side, maybe a couple non-qualifiers (and I'm only guessing that is why those guys aren't appearing on the official roster) helped open the door for Tulley-Tillman (same position as Neeley) and Jelani Hamilton (same position as Jest). Maybe it opens the door for another late grad transfer or two to also still join.
