No ways would he win a HW title. These guys are all too big and skill only gets you so far. He's lucky if he goes the distance with Kovalev
Not sure how Ward's body would look at 200+ pounds. I think at Andre's age hes a bit late for a HW run. By the time he finishes up at LHW he will be ready to retire. When he said he was going to HW I never took it seriously.
How can American pussified Protestant Christian beat a ferocious Slavic pagan? Son of God vs Son of Perun
Short answer: No, the HW guys are too big for him. Although, I do sometimes wonder whether he might have beaten Martin or even Lucas Browne. It's not impossible.
Its good to always aim high. When cameras are running most boxers always boast about doing things they know they most likely wont be doing.
