I don't think a Spencer vs. Manny will ever happen. Neither will Crawford vs. Manny. I doubt the camp of Manny will allow such very risky matches. They are now protecting the old man from facing very talented younger fighters such as the two fighters I mentioned.
Manny Pacquiao is still a great fighter but I love Manny Pacquiao that I don't want to get him hurt, these two boxers Spence and Crawford can hurt him because they are to dominant, they are at the peak of their skills and power, let these two boxers have it and fight each other and just leave Manny, I like Manny's like fight to someone body like him like Mayweather if he still likes it. or Mickey Garcia.
They didn't said that when Manny fought Thurman who is unbeaten that time, so there is a possibility that either Spence and Crawford can get into Pacquaio if the money is right.
It's a tough win for Spence I would say, but it is a tailor made fight for this comeback, yes everyone give Garcia a chance, but Danny can't adjust in fight and we see it as the round progresses he still looks for that timing to land his left hook, but Spence is too smart as he anticipate it throughout the fight.
