If he retires 50-0 he will be a top 15 ATG. If he retires 49-0 he will be a top 20 ATG PBF already is a top 25 ATG.
I'd say it could arguably get him into the top 20, around about that region. What about Pac, if he were to win where would it put him do people think? I'd say again somewhere in the 20-30 range
If he wins, and depending on who he fights afterward to finish his career, I'll have him firmly placed in the top 20 of all time. It's possible he could surpass 50-0, have ten wins against hall of fame fighters, have almost 30 wins in title fights,, lineal champ in 4 divisions, arguably the greatest SFW ever and the current simultaneous lineal champion in 2 weight divisions. The cap in his feather would be to beat the other great fighter of his generation. There have been some incredible fighters in the history of this sport and it'll be hard for him to crack my personal top ten, but if he fights 3 or 4 more times against quality opposition I just don't know how you can keep him out of the top 20. If he goes on to surpass 50 wins with an unblemished record, Id rate him at that time over pernell Whitaker, a guy whose widely considered a top 20 fighter ever.
That's why I said in THIS regard. The odds don't mean it'll be a tough fight. The odds don't speak to the level of competitiveness. Would I rate the victory higher if it happened in 2009? Yes. But me, personally, I IGNORE the odds. The odds are what people THINK and where you rank someone is all subjective. Maidana was a huge underdog to Mayweather and look how that turned out. He gave Floyd hell. Should we discredit the victory just because people didn't give Maidana a chance? And since you take that into consideration the way you do, that means you'll give Pacquiao more credit for winning than you would Mayweather.
