What would be more impressive / who would get more credit?

[Simurgh]

GGG knocking out Ward at 168 or

Manny knocking out Floyd at 147 ?

[-Kev-]

GGG KO'ing Ward because he hasn't KO'ed any one that fans in general can agree was all that good, and Ward is in his prime. Going from fighting JMW's and fringe contenders, to KOing Andre Ward would be a feat.

Pacquiao has at least KO'ed Barrera, Morales, Cotto, Hatton, and is proven with good fights against Marquez and Bradley, add the fact that Floyd is past prime.

Some good points.

How about Danny KOs Floyd?

nobody cares about ward, and mayweather got legion of haters, it would be heaven in earth when someone KO'd his ass

[Light_Speed]

GGG knocking out Ward would be more impressive because there's a big difference in resume and accomplishments, unlike Floyd and Manny, and Ward is bigger than GGG and still in his prime.

[Dirk Diggler UK]

Pacquiao KOing Mayweather would be more impressive.

Pacquiao looks past his prime and hasn't had a KO in years. Knocking out one of the best defensive fighters in history would be impressive.

Ward was KD'd hard already by Darnell Boone. Floyd has never been in that situation. And I've never seen Floyd get tired or lose composure the way Ward did in the last couple rounds against Froch. Ward is more vulnerable IMO.

I think Pacquiao KOing Mayweather gets more credit. Mayweather is a much better fighter than Ward and nobody has ever even cleanly knocked him down. GGG is a great fighter and I think he could spot Ward the 8 lbs. of weight and KO him.

[junior gong]

Pac Ko'ing Floyd simply because Pac is so badly faded. Both would be hugely impressive, Ward Ko'ing GGG would be pretty damn impressive also.

[bojangles1987]

Even past it, Pacquiao is an ATG and it shouldn't be that much of a surprise if he stopped Mayweather.

I'd be downright unbelieving if Golovkin beat Ward. If he stopped him, it would take a few days for me to process it.

Agree for the most part.

Mayweather has been buzzed by Corley, Judah, and Mosley, but never really been put in a bad way.

But, a GGG stoppage of Ward in the somewhat immediate future would be very impressive, as Ward would be still be considered more into his "prime".

Manny has slipped, but it's not like Mayweather is getting any younger either.
