What percentage chance would you give Tarver vs peak RJJ?

probably even

 

Roy had a glass chin and Tarver hit hard. That makes perfect sense to me.

 

He was coming in off of his rematch win over Johnson.

He had a lot more left in the tank than what Roy did.

 

It doesn’t make perfect sense at all.

He knocked him out once in 3 fights.

And Roy was completely depleted in the first fight, and he was coming off of back to back knockout losses for the 3rd fight.

They fought 26 rounds.

So if he could only knock him out once in 3 fights when he was faded, the chances against the Reggie version of Roy, would not in any way have been high.

Again, Tarver was a very good and dangerous fighter.

But your estimations have zero logic to them.

 

Basically this.
