Dana just needs to compromise I would think. Ngannou probably wants bigger money, so instead of Dana giving him the money directly, allow him to have a few boxing fights. I'm not sure why the UFC puts it in the clause of the contract that they can't fight in other sports. It would probably be beneficial because you keep the fighters happy, and you also put UFC fighters in the limelight, and in front of a new audience.
For example, I was originally a boxing fan, never even considered watching the UFC because I fell for the appearance of it rather than actually what it is. I always thought, I don't want to watch people beat on each other to a inch of their life, but doesn't really sound like fun. I was the typical outsider thinking that the UFC was for thugs, and boxing had more honour. Though, obviously now I realise how stupid that was without actually giving it a chance, I'm now a bigger MMA fan than boxing, in fact I literally only watch the big fights in boxing nowadays, I couldn't care less about it otherwise.
So, I assume that getting these fighters in the spotlight, could prove beneficial to Dana. Dana should be upping the wages on principle alone considering how much PPV buys they have, and how low they're paying them in comparison with other professional athletes. However, I think Dana by offering fighters the chance to fight in boxing fights once or twice a year, but still restrict them from fighting in other MMA competitions could well be the way to get a happy middle ground with the fighters.
I thought the fight with Gane was incredibly close, Gane seemed to be too good moving around for Ngannou to get the connection, but Ngannou showed he can adapt, and he does have other tools to his belt. Obviously, when he was on top of Gane he effectively did nothing, but control. So, he definitely isn't brilliant at it, but its progress, and I want to see Ngannou stay in the UFC for a few years yet.
It's a gamble for Dana to do that really but I think he knows that once a star had reached its peak, will ask for more. Not saying it's bad that it goes above Ngannou's head. It's actaully good to ask more and Dana knows that if Ngannou earns big in boxing, he may not come back. It's the nature of man to desire more. Ngannou has something in mind also since he already has his own foundation.
And true. I also can't see a significant shot from Francis. The only I think that made him win is that he got control over Gane on the ground. Gane is fast in avoiding and blocking.
