It would be nice if Goldberg signed a legends contract. It would be mostly for a DVD set, come out with some Retro T-shirts, put him in the WWE game, and have other merch with his name on it. Also like someone else stated maybe a movie role or two.
As for if he will wrestle again, he has said in the past that he would like to wrestle again so his son could see what he is known for.
His last match in WWE agenst Brock was bad because everyone thought it would just be power moves. But it turned into just like 15 minutes of being a test of strength with alot of dead moments. But there were reports that him and Brock know that stunk and rumors that him and Lesnar still talk and Goldberg and Goldberg may of reached out when he heard Brock was back with the company and was trying to see about putting on another big money match to make up or the WMXX match. If that's true who knows.
I hope he well come back for some apperiances and a few matches. I don't think he will come back to put anyone over. But if he comes back I would like to see him mix it up with some names and not the jobbers. Also, he would be a much better surprise entery into the Rumble then some of the people that they wasted spots on in the past.
