They'll be slingin leather, as both throw well above wgt. class avg. and land above wgt. class avg. for power punches. IBF featherweight champion Gradovich is busier and pays for it defensively, as opponents (Dib I & II, Munoz) landed 39% of their power shots. Undefeated challenger Jayson Velez landed 7 jabs per round vs. inferior opposition (Nguygen, Sanchez II)- he'll need that stick to hold off Gradovich
