Yeah that's weird how some people just cut a lot easier than others. Look at Mosley who took Cotto's punches for twelve rounds and barely had a mark on him, yet little Joel can do that to Katsidis face. I don't think cuts are necessarily a betrayer of power though. Some guys get knocked out cold without being cut. Anyways, Katsidis might not be a huge puncher but Casa was definitely dazed a couple times.
