Only if time travel is somehow involved. Here's a National Library of Medicine article/book review on the history of HIV/AIDS.

"The earliest identified isolate of HIV-1 comes from an unknown male in Kinshasa, Congo, in 1959. The first identified patient with HIV infection and AIDS was a Scandinavian man in the 1960s, who had visited west-central Africa. Then came sporadic cases among gay men in the United States and among Haitians in the 1970s, leading to the global explosion in the '80s and '90s and the literal decimation of peoples in several tropical countries."

I'd say don't source the history of diseases from NFL players, but those who would take my advice seriously probably don't need it.
