As a devout outspoken fanboy of both, and can say sadly, without even a shred of doubt in my mind, Kovalev gets violently KTFO here. Therefore I have zero desire to see this match.
Smith would knock Kovalev cold at this point. Kovalev's range-finder jabs and diminished speed, timing, and power wouldn't be enough to keep Smith off of him. And his punch resistance is so poor, any good power punch would have him going, if not outright gone. Honestly, Kovalev needs to retire. It's over.
Kovalev's Chin is made from the same material as Russian dolls. Layer upon layer of fragile Porcelain. It is quite frankly an utter disgrace. Hot dog stand attendant Smith would blast him back into the Bolshevik Revolution with a pawed rangefinder jab.
I believe Joe's a construction worker as well as being a top pro. That's old-school and you know that's a real man right there. Smith might KO a Kovalev past his best these days.
Smith via brutal KO. Prime Krusher would be one of the few current LHWs I'd pick to KO Smith but this emaciated drunkard shot version gets taken out in ugly fashion
