Can someone explain what the Frazier–Ali teams were and links that were recorded on the internet?

I was looking on Wikipedia on Tony "TNT' Tubbs because I heard he fought under the banner of the Ali team or whatever it was called, looking at his amateur career he was in some event that consisted with Ali and Frazier teams in his younger years. Does anybody have a better understanding of this or have any recordings of these fights???

Here is the wiki if you want to see what I am talking about: https://en.wikipedia.org/wiki/Tony_Tubbs

 

Does anybody have information on the Ali-Frazier amateur fight links?
