It's not just about business for Strikeforce, though ultimately that's what is going to swing Scott Coker's decision, and he is the one with the pull over these matchups.
I agree that from a business standpoint, it will hurt them in the long run because of the weight cutting and things of that nature.
It's also an issue of the interests of the camp. There's not much to gain and a lot to lose for Diaz. If he beats Jason Miller, what does he gain? A win over a middleweight (a division that he has no interest in fighting in long term) that doesn't seriously improve his international credibility as a welterweight, that doesn't give him another title defense and that doesn't help him build an argument for himself as either a legend killer or a legend himself.
But if he loses, his legitimacy as the champ is inevitably going to be challenged, his confidence gets shaken and his ability as a draw for Strikeforce (which is important for negotiating his contract) is going to be substantially diminished.
If you're trying to make the "man up and fight" argument, that's fine, but the reality is that fighters at the level that Diaz is at can't afford to take grudge matches. Realistically, that's possible for guys like Hermes Franca when he fights a guy for a dollar, at a point where he wasn't in the top ten and wasn't staring down a title shot.
The problem is that Diaz is still provoking Mayhem. For example, Diaz threw a water bottle at Mayhem backstage after the KJ fight. How can you do things like this and still expect to make demands? If he wants to keep playing this role, then he needs to eventually step up to the plate.
But this is a time when Diaz is finally trying to focus on establishing his legitimacy as a title holder. Strikeforce is finally bringing in competition for him to defend his belt against, and he is finally starting to realize that fighting in exhibition matches is not a good way to establish a ranking.
Does he have an obligation to sack up and fight a guy that he's been dealing with a grudge match with for a long time? You can make that argument.
But the reality is that it's not good for his career, it's not good for the fans and it's not good for the organization that would end up putting the bout on. So, why should we entertain that obligation over the financial interests of the organization and the possibility of more interesting fights that have a title on the line and, as a result, more relevance?
James Toney keeps talking about how he should fight Wladimir Klitschko. Is it in anyone's best interest for that fight to happen? No. Is it the best fight out there for the fans? Not really.
I am not really speaking from a business standpoint, I am responding to the fact that the Gracie camp keeps talking about the fight, but makes demands about a catchweight. This whole ordeal was started when Diaz made the decision to attack Miller.
So why should I care that the fight isn't happening? What's the motivation of the fans to push for it and (not at all separately) what's the motivation of promoter to try and get these two guys to sign the contract?
