Wehn Joe Louis was preparing for the second Schmeling fight, he had Henry Armstrong and Jack Dempsey in his camp.
Nigel Benn had a great camp for his Iran Barkley fight - Freddie Pendleton, Adolpho Washington, Leslie Stewart and James Warring. For his DeWitt fight he sparred mostly with the Russian amateur team because they kept their 'fence' up when throwing like DeWitt did, they were over at that time.
