There is a SI Vault in which Holmes described his times as a sparring partner for both Joe and Ali. And yes, Holmes said he was trying to emulate Ali’s moves for Joe’s benefit in order to prepare for their rematch in Jan 74. In hindsight, Larry should’ve been holding and clutching on to Joe instead to perhaps allow Frazier to devise a remedy for same - because Ali ultimately clinched Joe to death in fight # 2. Lol.
