I tried to get impressed with the Peterson brothers, and while they're well rounded, they don't do anything overly impressive. So far they've won their fights against limited opposition and their knockouts come by accumulation. Peterson probably has better defense than Ortiz, but I don't see much difference in handspeed, and Ortiz hits much harder. I can see Ortiz overwhelming Peterson and knocking him out. I think the Peterson brothers are still a work in progress. Right now, they're nothing to get excited about.
