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.
I doubt that's the reason why Garcia and Davis doesn't want to fight each other. Honestly every fight of both Garcia and Davis, they're always become a favorited boxer and they're not become a challenger. This because they're don't want to lose and ruin their undefeated record. Fight with Haney obviously will make they become underdog and there's a big possibility they will lose. Moreover there's a news if they're looking for move to higher weight division.
Whatever it is, it's still unclear what Garcia and Davis wanted because they could fight anytime if they wanted to, maybe, just maybe, they are still building the hype to make sure that their fight will sell out in case they will make it happen in the future. And I think what you said was just a rumor, we can't either confirm if they're really looking forward to climb the next division.
