Jones doesn't have better striking lol. He got out struck by Reyes and Santos. Jones overall game has regressed so much.
He couldn't grapple Santos or Reyes and honestly his grappling/wrestling didn't look that good against Smith. Glover and Raktic both looked better grappling Smith. People always talk about "Oh jon will out wrestle him, but he hasn't had an impressive wrestling performance in YEARS.
2020 Jones gets beat up standing against Jan. He might win a Reyes style decision where his inhuman durability allows him to out last Jan but Jan's strikes are more potent than Reyes.
Jon Jones is a great fighter, the fact that he doesn't take MMA that seriously, trains at an outdated gym with a style that isn't improving and still managed to scrape by undefeated shows that. But his days were numbered and he knew it.
