Pacquaio days as an elite WW are over based off losses, choice of opp and new faces

Manny Pacquaio is one of the greatest fighters of our era but their is beginning to be a change in the guard of the welterweight division Welterweight is such a stacked division and filled with so many hungry fighters, I doubt Manny's body can take the punishment it will take to get into shape to beat those guys, even though he still possesses the know how and some of his explosiveness....he just isn't willing to take the shots necessary to defeat fighters who could possibly outbox him. Manny made his bones at welterweight years ago against DLH in 08, Cotto and Clottey back in 2009-2010....but there has been a huge drop off in his level of opposition since 5 years ago.....in the past 5 years Manny has only defeated 2 top ten welterweights.....a 40 year old shane mosley who hadn't won a fight in 3 years and Tim Bradley who is good but hasn't done a lot at weltweight himself. Getting kayoed in 2012, and fighting 2 no hopers in Rios and Algieri padded his record but neither were ranked weltweights......Bradley was at the time after beating Marquez, but what has Marquez done besides kayo Manny at 147? After the loss to Mayweather, Manny is 3-3 in his last 6 fights.....he is still ranked highly but I don't think he deserves to be any higher than maybe 4 or 5 Manny is a great fighter, but add the fact that he is 36, and has a 6-12 months out because of his "injury", I think his days as an elite welterweight are over
