Great Pro's Even Better Amateur's

We all know of great amateurs who for whatever reason couldn't translate their success to the pro's (Breland,Gonzalez,Reid etc),or guys with limited amateur careers who were great champions but what great pro's were even better amateur's?

An obvious example that springs to mind is Kostya Tszyu who whilst imo a great pro fighter he was an awesome amateur with a record of something like 270-12.

My knowledge of amateur boxing is very limited so any other examples you could give would be appreciated.

 

That's a very good example mate.
With all that Lewis did in the pro's you tend to overlook his amateur credentials (the Bowe Olympic win excepted) which were fantastic.

 

That's an amazing record but I'd have thought Ray was still even better as a pro.After all he had a record of 130-1 as a professional as well at one point and that 1 was a loss he avenged multiple time versus La Motta.

 

Did these two achieve much at international level as amateurs?

I only ask because you see some guys with brilliant amateur records which are dubious in the extreme.For example 90's Heavyweight plodder Courage Tshabala (?) when he was an up and comer boasted of a 70-1 amateur record with 70 first round KO's yet was as clumsy and unskilled a fighter as you'd see and must have amassed his record against drunks and hobo's.
