I believe they should win, it would solidify them in the top-tier of the WWE with a win at Mania against a team like Sheamus, Orton, and Ryback.
If they lose, it wouldn't hurt their careers BUT it certainly wouldn't help their careers and a win by the other guys really doesn't do anything for them at all. So it's a lose/lose if you ask me for everyone involved.
I'm guessing right now a buildup for an Orton heel turn will come out of this match. We'll see, but that's my guess anyways.
