Fights that could have been even better had they gone 15 rounds instead of 12?

[PRIDE OF BOSTON]

Some suggestions

Barrera: Marquez
Hopkins: Taylor 1
DLH: Mayweather


What other fights could make the list

Barrera: Marquez was so close. Hopkins was pressing in the championship rounds to make up an early deficit. Perahaps Mayweather would have dominated Oscar towards the end?

Here's a few... I took your first two, Miles

-Hopkins -Taylor: Just the first one as JT had pulled well ahead in the second bout.
-Oscar -Mayweathe: I think Oscar won the 12th and hurt Mayweather with the late barrage.
-Ivan Robinson -Arturo Gatti (fight #1): Nothing needs to be said
-Paulie Ayala -Johnny Tapia (fight #1): Please see above
-Micky Ward -Emanuel Burton: I know it was only 10 rounds! I'd watch 5 more rounds of that!

Mayweather wasn't even stunned at any point during the fight..

In the last 20 seconds of the fight Oscar landed a crisp shot that wipe the smirk off his face... He didn't stager him or anything... Not even close but it was a "How do you do"!
