Well i would not consider what Ali did then running because he was throwing that jab so much the same with SRL when he Fought Hagler. PBF style is called running sometimes but it is a bit different then the style of Ali and SRL i would not consider SRL or ALI runners but i could be wrong i mean they did not stay still but on the same note they still were throwing a lot of puches and did fight on the back foot but they both come in and fight alot as well.
