Reply To: Who is Rav Shlomo Kanievsky? Is he being groomed to be the next Godol HaDor?

YO,
R’ Elazar Ben Azarya was chosen because he had Zechus Avos (which, it was hoped, would protect him from whatever K’peida Rabban Gamliel might have), but not because he had “rights” to the position. It should be noted that he was approximately four hundred years removed from Ezra.
