If there is a rematch clause then Tank will have to look for other opponents, but I'm not sure who is he going to face next, Romero is asking for a rematch with him, but I don't see Davis giving him that opportunity again as he said on the post fight.
Loma is still busy in his native country of Ukraine, while Ryan Garcia might be the logical option, or even Lopez if he can still make the LW division.
Romero has to move on, he will not get a rematch with Davis as that was a very clear win. Davis will instead look for an opponent that has a good record and could him create a good fight. Romero was given a chance, his chance is now over.
That's a sign though of sour loser as he can't move on. And I agree that he has his chance but didn't make the best of it. Rolly might have a good boxing future because everyone talks about his power, but they shouldn't let him fight the champion this early at his career because he is going to be destroyed as he lacks the experience. I'm thinking that he could be a good match against Isaac "the Pitbull' Cruz next. Two hard nose fighter with very good power. But we will see what Floyd next option will be for Romero.
Losing the first time via knockout is such a bad experience but Rolly will learn, but he should change his attitude and maybe change his trainer, it's not always power that wins the match it's always timing and getting the upper hand at the right time, and this is why Haney and Kambosos are ahead of the pack they are patient, they are not seeker they know that it will come when they work on the opportunity and the right timing and this is what Romero totally lack, Romero is good for level B fighters but for level A he'll have a hard time adjusting.
