He can still beat pretty much anyone at WW. People seem to forget that pac is a part time fighter. He only trains and deal with boxing when he has a fight. He has another full time job, a very demanding one at that. The fact that he can still compete at the elite level is incredible. Anyway, yes he can rise again and even better if he gives up the politics gimmick, unfortunately that is very unlikely.
Of course... He fell to a fellow HOF and his all time rival. Especially with Top Rank in his corner, I suspect there will be several more successes from Pacquiao in the ring until he finally calls it a day.
based on his last fight before the KO, pac seem to still be closer to prime than shot. if he could just gives up on his other interests and focus on boxing, he can definitely rise again.
The best thing that could have come out of IV is future opponents thinking Pacquiao is spent and attacking him resulting in more classic exchanges.
When you get slid worse than Hatton which I call coffined. Worse than Roy Jones, Khan, Arce, Jason Litzau, basically beating out so many great contenders who got slid worst, Manny is by far at the top of that category. The term I made up for Manny's KO was trap doored because there was actually a ringside spectator that thought Manny jumped into a trap door, thats how ludacris that KO was . Please retire Manny .
