Who beat Roy Jones Jr the most decisively?

[El Angel]

Johnson. Dominated from the beginning until he knock him out cold. Calzaghe got knocked down himself and Tarver's knockdown of Jones wasn't as bad as Johnson's.

[Bushidō]

Roy had no shot at all of beating Johnson's pressure

[Benncollinsaad]

Glen Johnson fooked him up real bad. So there's no doubt. Jones beat Tarver's knockdown, but he was left lying for 2 minutes after Glen's knockout.

[Chr0nic]

jones had no heart for johnson

[Mersey]

Johnson almost certainly was the most impressive.

LMAO at the first option : Montell Griffin by DQ.

Seriously, Roy Jones Jr was stopped more decisively by Tarver because he was at this point the most highly regarded fighter in the world and a HUGE favourite. Virtually undefeated, the close win by Roy and Tarver's good performance were thought to be a fluke. All picked Tarver to get demolished in the second fight. RJJ's knock out loss to Tarver is a turning point in recent boxing history.

The Glen Johnson was more violent in a pure physical point of view but RJJ was already weakened by Tarver's win over him. It was easier to Knock him out.

That's why i conlude Tarver"s win is more decisive.

Tarver shock the World so i say Tarver.

[bojangles1987]

Glen Johnson is the only man to beat up Roy as badly as he did, and the KO was brutal. Calzaghe is close, but the Roy Glen beat was closer to being a factor then the Roy Calzaghe beat.

I'm not sure I just know Johnson fought the weakest Jones of them all.
