Still same company buying a stake though... just all rumours.
It isn't the same company.
Redbird is basically Gerry Cardinale, Redball is Cardinale plus Beane, plus the likes of Scudamore.
Redball was a SPAC specifically setup to buy a stake of a sports team with investors money and would have been listed. Redbird is a private company who will be using existing funds.
