Smackdown needs a good face character - who have we got at the mo? Mysterio and Morrison?
And, ahem,
Undertaker 
It will be cool though to see
Edge as a face, hopefully it won't be the character gets diluted and for want of a better word, loses his "Edge", the guy his cocky and will do anything to be champion, face or heel, that shouldn't change, if he starts hugging
Mysterio and being all nicey nice, it'll ruin a character that has been built up so well since he was forced to turn heel after those, real life events...
