Mark Henry made a surprise return at Elimination Chamber as a babyface, but appeared to be a heel again during his match against Roman Reigns the following night on Raw. The latter is ultimately the better role for the World's Strongest Man, and reigniting his feud with John Cena over the United States Championship definitely has a ton of potential. Their matches in 2013 were extremely entertaining (and also included one of the best promos of all-time thanks to Henry), and while it's hard to imagine WWE Creative coming up with anything drastically new for these two, that doesn't mean that Henry accepting Cena's challenge one Monday night wouldn't at least result in a fight well worth watching. Henry probably isn't someone who will or even needs to take the title from Cena, but if the WWE are going to re-establish Henry as a dominant monster heel, then an impressive showing against the US Champion would definitely be a way of quickly achieving that.
