Please allow me to invent some infinite wisdom on the spot. No. Fucking. Way.
Why? Why should Goldberg be allowed to waltz back into not just WWE, but the bloody main event of their premiere showcase PPV, undoubtably getting paid a shitload and waltzing back off into the sunset at his leisure? What sort of message does that send to the rest of the roster?
Let's for a moment take a look at Goldberg's wrestling career. The man was fortunate - for whatever reasons - to receive possibly the biggest, most intense single push ever seen in the industry. Most of the matches in his 'streak' were just plain squashes, meaning his work rate was bugger all. He never had to work his way up the same way so many others had to and I'm pretty certain he was promised from the beginning he'd be pushed all the way to the top, effectively cutting in line.
Goldberg has no interest if he is not a top guy - you can believe that. The Rock gets so much criticism for walking away from the business yet Goldberg did the same and the fans continue to be fascinated by him. Goldberg was also very ordinary in the ring and a stiff worker to boot.
So, to main event Wrestlemania 27? Only to lose? What's the point of that? To end the streak? Again, what's the point of destroying something like that just to walk away again? There isn't one.
The only way I can see this working convincingly would be if Goldberg signed a 1 year deal with WWE and they build it up for Wrestlemania 28. C'mon Bill, give something back!
