Goldberg and Crimson still have an angle. Crimson's streak lasted almost the same amount of time as Goldberg's. Crimson's was said to be over 470 days whereas Goldberg's was about 490. They could still go for a 'my streak was better than your streak' angle. And I think if Crimsons cut a promo about his streak, saying that it's a feat unparalleled in the history of the company there's also fuel, as Goldberg could come out and say it wasn;t the longest streak in ANY company though.
Obviously Crimson is someone TNA wants to push right now, and I'll hold my hand up and admit that his recent work, his in-ring work AND his promos, have been the best he's produced in the entire time he's been there. He is a viable candidate for a short 1 PPV roll I think. But there's better candidates for him to feud with overall, because we don't know how long he'll be at the company.
From the top, I'd probably wnat him to feud with:
Samoa Joe - n terms of wrestling style, Joe is the guy most similar in the whole company to the style fo work Goldberg used to employ. He doesn't squash guys, but he can pull off scarily dominant with ease. I can actually see these two producing a mouth-watering and good quality feud and even matches.
Roode - With the roll he's on, this would almost have to happen anyway. I'm sure with a wrestler of Roode's quality, we could produce a decent match out of it too.
Magnus - I'm sorry, but I just put a hell of a lot of stock in this guy as a future player in the company. He can wrestle, he can talk, and he's only about 25. He's like the Cody Rhodes of TNA. I don't know how to engineer it but I think Goldberg should go out putting a guy over this time out, and he's a good a contender as any.
