I was torn between 10-15 and 16-20, but I honestly cannot name 15 better HWs, so I voted for the former. You cannot ignore the record and the sheer domination over the division, no matter how shitty the division is. And you cannot ignore the KO percentage, although many of his opponents have entered the ring with shit in their pants.

I also have mixed feelings, as someone said earlier. He dominates, but is boring. Excitement has to be factored into the equation, at least IMO. Wlad plays it safe, and his opponents accommodate him. I'd rather watch paint dry than to watch some of his fights. On the other hand, he's got a good 4-5 years left in him... and one can only hope he'll get tested by some of the young up-and-comers.

Another downer for me: Three ugly KO losses... and only one of them was avenged.
Total opposite from someone like Lewis.
