#2 The new leader of SAnitY?
Eric Young is a big name in wrestling. However, there exists a huge portion of the audience that may be unaware of who he is. WWE may want to associate SAnitY with a big name to get them off to the right start. A superstar who could join their ranks could well be the Lunatic Fringe himself.
This would effectively mean that Ambrose would become a SmackDown Live superstar, going forward. SmackDown Live could benefit from Ambrose' star power. SAnitY falls in the grey area between heel and babyface, and this could be an interesting change of character for the ultimate babyface, Ambrose.
RAW is a pretty stacked show anyway. We are afraid that if Ambrose returns on RAW, he may get lost in the mix.
