#7 Zack Gibson and James Drake

No matter where Zack Gibson and James Drake turn, they have good opponents waiting for them, whether it's a renewal of their rivalry with Moustache Mountain, a clash with Oney Lorcan and Danny Burch, an eventual showdown with Gallus, or more. The only thing that's really working against them right now is their placement on the UK brand, which is one of WWE's most obscure, which means more people won't be able to watch them.
As for who eventually takes the titles from them, it's still anybody's guess, but as we mentioned, there are no truly bad options right now, which is more than can be said about most other champions and their potential title challengers.
For however long they reign, they should be in line to have good feuds and matches without anything dragging them down.
