Yeah, I think this is when Triple G was at his peak and destroying everyone at Middleweight and cleaning up the decision. So there are no more challengers and he is looking for money fights that's why he showed interest to fight either one of best, Floyd or Manny.
But again, the same arguments we have today, Triple G is too big for two, specially Manny Pacquiao. And we eventually saw Floyd and Manny fight that year, making the biggest boxing fights in history in terms of revenue.
Yes it was a history but people will not remember it as a good fight as it was a boring fight IMO.
But this GGG fight against Manny, I believe it's not gonna be boring, one fighter will be hurt badly as both fighters loves to fight toe to toe.
GGG might be big for Manny but I believe Roach knows better than us.
