If he is able to keep it at Mania and the RAW After Mania, then yes, he'll get to 1,000 days. I feel like there's a growing chance that he may retain, but I also feel like it's time to move on from the reign (no pun intended) of the Bloodline. And there's ways to keep Roman in the spotlight-post title reign. He can become paranoid about losing his spot as the Tribal Chief (despite all that he's accomplished) which will either lead to a match with The Rock, or the more likely scenario, another program with Jey, where Jey finally proves he can beat Roman and doesn't need him anymore. Roman has done a fantastic job since he came back from hiatus in 2020. I think all of the fans were happy to see him finally come into his own, and have him not be a product that Vince wanted people to instantly cheer for.
