Who unilaterally decided that someone has to be a champion to book a 'superfight'
Two marquee names in the sport who would otherwise not meet in their own division is a superfight to me.
You're entitled to your opinion, but I also disagree.
Does no title being on the line mean it's not a superfight? Not necessarily.
Does the fact that one guy had never even been champion in the biggest organization mean it's not a superfight? Not necessarily.
Does the fact that both guys are coming off of consecutive losses mean it's not a superfight? Well, I guess not necessarily, but that's not really ideal.
Does the fact that neither guy has fought in more than a year, with one nearly out for two years mean it's not a superfight? Again, maybe not in ever single possible case, but that's really, really not ideal.
Does the fact that fans have long been clamoring for one of the fighters to fight in one of two superfights but that this isn't either of them mean it's not a superfight? That one is a little harder to ignore.
Any one of those things on its own might not disqualify Silva/Diaz from being a sueperfight, but all together I can't call it one.
