I was thinking how it would be if we saw a round between two fighters then subsequently for some reason the fight was unable to continue after round 1 and re scheduled - how would this change our opinions on the fight?

For example:
Broner vs Maidana - Broner heavy favourite before - but would he have been even a fsvourite if everyone had the chance to see the first round first?

Hatton vs Mayweather? Mayweather favourite before but had a stumble in round 1 etc

Lewis Tyson - Lewis the favourite - but tyson had a good first round etcetc!

Whart would your thoughts be on the fights above and others!?
