Imho the best what Haney could do is to organize a rematch on any conditions. Not asking for more money, double-triple doping check, not crying that he Garcia won unfair and etc. But stay silent, focused and beat crap from Garcia via KO. It was Haney who has landed on the butt in the fight, not Garcia. So it is 1:0 in Garcia favour in any case.
We have such a popular quotation - "dont swing fists after the fight". What is done is done. Now turn the page and prove that everyone were wrong.
I like the suggestion that Haney should prove himself so people can see that he didn't really lose that fight if it was fair. A rematch will settle who truly is the better boxer between the two. If Haney wins, it will put to rest the debate about who is superior. Haney having one loss already looks bad, especially with all the complaints that suggest he can't accept defeat. He might have lost a lot, but he needs to be direct to the point. If he wants a rematch, he should organize it as soon as possible. I'm pretty sure Ryan is more than willing to give him another loss.
Ryan is nowhere to be found in the ranking already.
He is suspended and if ever he returns in a real fight, he will demand the rules be in his term. Or it will just be exhibition fights like Jake Paul is doing.
Worse loss of Haney, he couldn't get over that he has to make sure Ryan gets punished for defeating him fairly.
