Vitali Lennox and Wlad Fury may have been bigger, but neither were as hyped as this one coming in. This is a unique fight because it's the first time we've had two well respected HWs, in a 50/50ish type fight who are both over 6'4 and 230.
This is definitely the most hyped HW fight, world wide. No idea why so many fans justify claiming there's some new B.S shw division. Fyi: this isn't amateur boxing with its own separate SHW division to make it "fair"
90 thousand people in a full stadium.. it doesn't get much bigger than this in terms of boxing events.
