Rui Hachimura already got his teammates hooked on Japanese chips
Troy Brown Jr.: "Bro, Rui been on the team for like two weeks and he
already got us on!"
Jemerrio Jones: "It's really good tho."*
It is an informal idiom used by the newer generation to show how much they like something - he is talking about the chips.
There is more context to the text if you click on the twitter link. The author is talking about how his teammates “got him on these chips” without the “hooked” - “he got me hooked on these chips!” It means he likes the chips very much after his new friend, Rui who recently joined the team introduced them to him.
(note: “Rui has been on the team for like two weeks and he already got us on!”) and this is reinforced by the later text, saying “It’s really good though”.
