All the same, WWE would be foolish not to capitalize on Dolph's current momentum and the reactions he's getting. It seems like they are going to try and keep him high on the card, too, but I would be shocked to see them re-book the Rumble and WrestleMania around it.
What I think is slightly more likely (though also fairly unlikely) is, if Cena loses at TLC, putting Dolph up against Lesnar at the Rumble. Lesnar would wreck Dolph, of course, but Dolph's work would help remind people of the beast Lesnar's supposed to be heading forward to WrestleMania. Then, Dolph can have a solid match with someone (maybe Seth, maybe Rusev, someone high up but not at the top) in the mid-card of WM.
I'd love to see Dolph get a serious run with the WWE title, but right now the spotlight's primed to focus on the ex-Shield members, most specifically Roman. However, I see no reason why Dolph can't have a moment like proposed here in 2016 or 2017.
