I don't understand exactly what's going on. Are kids not believing in CJH? Why leave so close to fall camp? Is this #28???
Yeah. I'd love to be a fly on the wall. Could be they don't believe in him... but others have very publicly stated their confidence and are telling recruits that the new staff is much better than the old one.
It could be simple honesty in some cases- "You don't fit what we're doing and may want to consider other options".
In other cases it could be personal or academic. If Middleton is not a pro prospect then why not either get a better educational opportunity or perhaps even make things easier academically.
Lots of potential reasons. There isn't likely a single one that covers everyone who left.
PS- the cash for play investigation is still out there. There is always the chance that a player was asked to go elsewhere because of involvement.
