FWIW, I don't care if you go thru your HBD life believing that a lost ratings point due to injury means a player can never reach his potential but please understand that this isn't a known fact. There's no way to prove or disprove that it is. Of course, if a player never returns to his previous high that is, indeed, a lost rating point that was not be recovered. And he did not, in fact, reach his potential a 2nd time.
