The Shield winning something that puts them immediately into the title scene.
Then.
Now.
Forever.
Depressingly. I'm assuming Mania is KO vs Jericho, non-title; Rollins vs Roman ver. 76; Rusev probably back with the US title, vs somebody; AJ vs Cena (maybe with Dean as a triple threat?); Sasha Vs Bayley, probably; Charlotte vs Dana - or, actually, maybe even Nia Jax; Becky vs Alexa vs Nikki Bella. Then some shitfest battle royale, AA vs Usos, Cesaro & Sheamus (who'll have taken the title off New Day) vs Hype Bros or some nonsense, Brock vs honestly who cares unless it's Sami Zayn and DBry's worked something through with creative for his samson/goliath thing.
This is all unless HHH wants to fight, in which case that's against Rollins, and my entire card above collapses in a heap.
EDIT: I stress, this is not my ideal. Ideally, Joe wins the Rumble, and says he doesn't want a title match - he wants Brock. Throw away the huge opportunity for the chance to take down Brock. And he's the one who does. That's how you monster him good.
