Chad Gable and Jason Jordan were an awesome team. Their chemistry, backstory of how they ended up teaming together, and the actual matches were all top notch. Both guys were destined for big things as singles stars too, but there was too much money on the table with them as a tag team to break them up so soon. Naturally, that's what WWE did, and it hurt both guys for a while. Hell, it literally hurt JJ so much he's retired now, while Gable has thankfully managed to get out of the bad booking hole.
Creeds are in a similar boat, as they are basically a re-do of American Alpha: two young, athletic, all-American wholesome jocks. However, this time, everyone is pegging one member (Julius) to be the star, while the other one (Brutus) is just kind of tossed to the side by most fans. I personally see Brutus as a fun, Otis-esque babyface that can be an asset to the company, but that's neither here or there. The point is that WWE cannot rush to break the two up just because they see Julius as the next big star. The Creeds doing extremely well as a unit thus far, and can help carry the tag division for the majority of the next decade alongside Pretty Deadly.
Julius is 29 years old, he has at least 5 more years before he hits his prime. WWE should do what they just did with Usos - establish these guys as the best tag team of this generation first, and then push them as singles stars afterwards. I trust HHH and HBK though, and hope to see The Creeds shine like the diamonds they are.
