Past fights and recent fights without the Marquess of Queensbury rules.

[Hoggmeister]

As most of us know the Heavyweight title match Between John L Sullivan and James J Corbett was the first to be fought under the Marquess of Queensbury rules, but ive always wondered how past fights and recent fights would have played out if the intervention of these rules hadnt happened. What do you guys think, and what fights immediately come to mind when you consider this idea?
