Lewis is greater than Fury tho ? That's not that bad of a dent. Bowe was arguably winning the rematch until the nutshots started, and considering the brain damaged him retiring wasn't a bad thing to do. Golota even after the Lewis fight went on to arguably beat Chris Byrd at least. I predict Ngannou won't half the success post Fury
Lewis might be greater despite his two ko losses. Fury's rep is down quite a bit but his 0 is intact unlike Bowe or Lewis. I want to see Ngannou again to assess where he is. Another camp and he can only improve. He has clubbing ko power and a solid chin. That much we know for sure.
Lewis avenged his two losses and the calibre of resume is light years above Fury's. Being undefeated is meaningless if you've not cleared out the top of the division, it's that simple.
