Ranking the 1st official title reigns of future active HOF fighters

I have chosen popular and active ATG/HOF fighters: Cotto, Holyfield, Jones, W. Klitschko, Marquez, Mayweather, Morales, and Pacquiao.

Among them we have the often regarded greatest Cruiserweight and Super Featherweight, two of the greatest Mexican fighters ever, and the greatest weight jumper ever. This really is a tough and interesting thing to look at. I am going by whatever the first "title" run they had was including the fight they won the belt and if they lost it as well as not factoring in non title fights during the title run.
