That's your right to not like Wlad, but...

" let me point out that the whole premise of boxing is to actually engage the other guy and try to knock him out"

...it has to be pointed out that Wlad has 53 KO's in 63 victories. Joe Louis had 52 KO's in 66 victories, for reference.

So if the whole premise of boxing is to engage and try to knock your opponent out, Wlad has done a better job of it than just about any HW champ outside of George Foreman. Technically, he has a higher KO percentage than Mike Tyson.
