I don't think this fight will be close and end in a decision because both fighters just need to land their best punch to make the fight over, both fighters' strategy is they need to land the first hardest punch.
Regardless of who will be the winner of this one, i think the rematch won't happen in a year or two because of Tank Davis' sentencing that will happen after this fight and the probability of him being jailed is too high but if a rematch is to happen i think Davis still has the leverage on that one even if he loses the first fight.
Yeah, this fight will end via knockout (just my prediction) and it will be Ryan Garcia who will be sleeping in the canvass this time hehe. That rehydration clause is too much for him and he will only be taller but not bigger that Davis come fight night.
Although a rematch is a possibility, it's important to focus on the upcoming fight. Despite many predictions against Ryan Garcia, he's sure to give Davis a tough challenge. If Garcia can't utilize his reach advantage effectively, he could potentially get knocked down or even knocked out, which would make a rematch less exciting. The first fight is crucial, and it should be a close and exciting matchup to keep fans interested in a potential rematch.
I believe that there's no rematch clause in this bout because if there is any, we will probably know about it by now. A rematch is possible depending on the outcome of course and there's this Tank's situation where he will get his verdict this coming May, so if ever he will get a jail time, that will mean that a rematch clause will probably expire first before he sets foot on the ring again as most of the rematch clause is only available for 100 days after the bout.
Before that, I agree with you mate, let's just focus on what we have on our plate now. We will know about the other information once this fight is settled, no need for us to rush about it.
There is a rematch clause according to this source:

So basically, Ryan Garcia will have to win this fight before a rematch could be evoked. Perhaps it was on the side of Garcia that he wanted to show that he can beat Davis either by knockout or decision win.
On the other hand, Tank Davis if he won, is not contractually oblige for a rematch and could probably end their rivalry with that one big win. Unless both of them moved up to 140 lbs and then face each other in the future for the belt. And that is the only time that Ryan will have his another chance to crack Davis again. So almost everything favors Tank here, including Ryan not going to weight more than 10 lbs before the actual fight, called rehydration clause.
