I'm still figuring it out what he saw on Ryan because personally, I'd pick Davis over Ryan. I may be wrong about this but I guess we will see once they share a ring.
Maybe he was challenge by Ryan Garcia and he likes to shut him up. Ryan could attract a good number of crowd as well, so in terms of revenue, there's still a chance that they will make a profitable fight. Actually, it doesn't matter if he start with Ryan Garcia, because if he beat him, he can have Davis next in line.
That may be the case and possible scenario, but I seriously think that Garcia and Davis fight is almost inevitable because both boxers are contesting to reach Haney, Ryan cannot go to Haney directly that is why he is teasing Davis because that is his key to have a fight with the undisputed champion, Devin Haney and I sincerely hope that this fight will happen soon.
