Crazy theory, but what if Finn wins the Rumble and decides he would rather move to SmackDown and face AJ for the WWE title, because of Japan and their TLC match? He's totally lost on Raw right now but he could flourish on SD if he moved over. There is precedent for this when Benoit went the other way and moved from SD to Raw in '04. Snark about the looming specters of Roman and Cena aside, what do you think?
There is zero chance of Finn winning the Rumble. I also don't think he'd necessarily flourish on Smackdown any more than RAW, because clearly Vince doesn't see whatever in him regardless of which show he's on. To be honest, I don't see that level of guy in him, either.
