Brewster would KO him IMO, Maskaev's slicker but not that slick and Brewster's better chin would pull him through. Maskaev would have to try and box and move a bit and try to hurt Brewster and take him out, which would be tougher to do versus Brewster than Rahman cause Lamon's chin is better than Rock's, cause I don't see Maskaev's chin holding up for 12 rounds against Brewster's pressure.
