A wild card.
With the possible exceptions of a cumbersome Great Khali and a conspiracy-saddled R-Truth, these two were probably the last guys you'd expect to have had success in the Elimination Chamber matches.
Heck, with face CM Punk and "lucky weasel" Daniel Bryan as the champs heading into WrestleMania (and face Sheamus needing to face one of them when they get there), they were absolute no-shots to carry heavyweight gold.
Which is somewhat disappointing, as the WWE doesn't take advantage of its opportunities (Royal Rumble, Elimination Chamber, Money in the Bank) to really make "anything" happen. Santino has teased this possibility already, coming in second at last year's Royal Rumble match.
Really, it's the timing of the Chamber and Rumble that prevent them from really playing up the randomness factor. Since the prize in each is essentially a main event in WrestleMania (though, really, the Chamber champions could just lose the belt on TV before the big one), WWE is under great financial pressure to push through big-time main-eventers.
And without being able to take advantage of one of these "anyone can win" events, neither Kofi nor Santino have any real potential of getting a heavyweight or WWE title shot in the future. Not without a significant change in the way they're used by the WWE and perceived by the fans.
Which is the main reason these two should be getting opportunities at the midcard titles.
