I have plenty of excuses for circa post 2000, just fell away from hardcore watch every fight that was available, to casual pick and choose any paricular fight that chose my fancy.
In part, think terrestrial tv moved away from covering boxing, and also the 90s was a thoroughfare of great UK boxers to follow, then waned spectacularly for me.
Back to the point, besides highlights, I've not seen Mayweather vs Pacquiao.
Not seen Ali vs Norton 3 either. Like many, a massive Ali follower and never really had the heart to watch the third iteration.
