Prime RJJ or current RJJ? Current will get his butt handed to him, and prime will win easily but fail the pre and post fight drugtests.
The look on Hopkins face after Kovalev knocked him down told me all I need to know. Jones would likely get brutally KOed.
Jones. Too fast, too elusive, and had one hell of a punch as well. There is nothing aside from power that sergey has over jones.
The scared troubled look on his face after getting knocked down then running the rest of the fight. Wouldn't matter if he was 20 or 60 years old. It told me all I needed to know. Kovalev is a savage puncher. Jones fought nobody with that type of power and still managed to get dropped or KOed several times.
Oh I fully agree that Kovalev has Chin issues. But I cringe at what his right hand would do to Roy's pea sized head and Glass Jaw. It would be brutal.
