As opposed to beating Mayweather. Which win would you value more?
I don't know what's so hard to understand. Of course I'd love Juve to win the Scudetto 20 years in a row... Just it might get a bit boring having no competition. That's where the 12-year old boxing comparison comes from. After 4 or 5 years, I'd probably not even bother to watch us play Lecce, Bologna, Siena anymore--just Milan, inter, Roma and the CL knockouts.
Having to struggle for your victories makes it more enjoyable. Well, that's just me. But I'm sure if we had to play Barca in a CL final tomorrow, Juve fans would be much more excited than Barca fans.
Point is not to take away from Barfa's success, just questioning how long can they keep the enthusiasm up. Most Barca fans I know are like, "Oh yeah, we play Real next week. Should be a great game. I hope Messi scores more than Ronaldo." Juve fans are like, "Holy shit, we play Milan 3 weeks from now. Can't wait for Chiellini to smash in Zingaro's nose. We need those 3 effin' points. If we win, we could go to 4th! Hell yes! Fuck Secco."
