Timothy Bradley (28-0) challenges WBO welterweight champion Manny Pacquiao on June 9th at the MGM Grand in Las Vegas. However, Bradley only has 12 knockouts among his 28 victories, a knockout percentage of just 41.3 percent. That is low, to be sure. But Bradley doesn't want to hear about that, either.

"Heck, yeah; heck, yeah," he said, when asked if he can hurt Pacquiao. "I put dudes on the canvas. People don't see me knock guys out with one punch. I put them on the canvas. I put Junior Witter on the canvas, I put (Lamont) Peterson on the canvas. I put, who else? I put Edner Cherry on the canvas. I put a lot of guys on the canvas.

"I can put him on the canvas, too, I believe that. I believe that, without a doubt. Look at me, man. Go look at Manny, come look at me. Come feel my bones, come feel his bones. Look at this picture right here. Look at them guns."

Of course, having big "guns" doesn't automatically mean a fighter has good punching power. That is common knowledge.
