The one I enjoyed most was Williams/Sprott 2, the small hall atmosphere was excellent, biggest, not sure, but Froch / Bute was quite big recently
Biggest can also translate to most important or most exciting. It doesn't have to be how many were there. example given - if you were at Castillo - Corrales I or if you were at Pac - Clottey, the variables are different. Tell me the fight that meant the most to you when you were there, and why, and how nuts the fans were, atmosphere, intensity.
Bonkers. I had to do the self reach around examination to see if I actually crunched out a rosebud. Thankfully it was a false alarm.
Biggest in terms of boxing importance would be Ward/Abraham. Title fight, Super Six, Armenians waving tons of flags countered by chants of "USA, USA." A great experience in all. Biggest in terms of excitement/anticipation: Rios/Alvarado. SoCal was pumped for that fight and the crowd was absolutely electric. HBO did a disservice by drowning out the crowd and making viewers listen to Lampley.
Williams vs. Martinez 2 Rematch of a very good fight - Crazy atmosphere - Middleweight Championship - Great Ending - and a Picture with the Champ after the Fight! Perfection for myself.
Peter/Wlad 1... for exciting wlad/Haye.. all the **** talking, crowd... all of it Vitali/Adamek in Poland was off the chart with the crowd
Ward-Froch. Sitting around a group of Brits with some disgusting mugs who damn near **** themselves when Kell Brook came out
Bruno vs Bugner Nigel benn vs Anthony logan Herol Graham vs Rod douglas Gary mason vs James Pritchard And many more!!!!
Wlad - Haye. Crazy atmosphere, **** talking with my friend who is Wlad fan, brits making it sound like Haye was the hometown boy and all that. Great event. Even when the fight didnt deliver, it was exciting to watch as both were capable of KOing each other at any moment.
