Gonna come off like the curmudgeon here but what the fuck ...
Well, the only classes I care about tend to be 147 or 154 - anything above becomes filled with middling European fighters that I believe are only champs or near champs because boxing isn't hugely popular anymore (Klitsco, Froch, Lee, Macklin, Josua, etc.) and there isn't good competition. For the record, I like Lee because he's Irish, but he's just alright. Nothing crazy special.
I like Kovalev and GGG, but there aren't a lot of guys willing to face them, and the competition isn't stalwart to begin with, so I just watch their fights and enjoy them without caring who they're really fighting. So again, when there's an actual threat, I'll pay more attention.
Andre Ward literally kills me. He's easily the best fighter in that weight class and each one up and down, but his inactivity is maddening. It is my opinion that he could be all-time great if he fought, and there isn't ANYONE who beats him (not even GGG, sorry), but alas, he doesn't. I dunno what to make of him anymore.
As for Cotto, Pac, and Mayweather, we've got to see how it shakes out. Boxing will only be rejuvenated after an abysmal 2014 if Mayweather and Pac fight. A second Cotto-Mayweather fight is great - I would love it - but it won't have the curb appeal that May-Pac would.
Honestly I just hope it happens to shut people the fuck up. I'm tired of hearing about it.
Also, fuck Amir Khan. I hate him.
