Goldberg would be good for the first 5 minutes. People would say "oooh i remember him...goood ol' wcw days..." And then what? is he capable of wrestling? or even better, to you want him to take the main-events? It doesn't seem a very sustainable idea.
I think Magnus or Samoa Joe will end up being revealed as a high up in Aces and Eights....if not 1 of them then maybe Bully Ray he does seem to show up at the end of fights and chase them off maybe thats his way of telling them they have done enough for one night...hmmm cant wait till BFG to see whos in the group!
