I don't hate Ryback but I'm not a big fan either. I do like that they are pushing someone new in the main event, but at the same time, I can't see him being some huge main event star in the future. Similar to Goldberg (as big as he was at one time), he'll fizzle out within only a couple of years at most. Unless he evolves past this mostly silent monster who just loves to destroy people, because there's only so many places to go with that.
I still don't get how anyone can say he is better than Goldberg in the ring. I'm not counting his Skip Sheffield days, just his time as being called Ryback, but I haven't seen anything impressive just yet, and I personally think Goldberg was slightly underrated in the ring. People act like he was like the Warrior, with only a couple of moves, but he actually had some pretty cool moves that he used to perform in the ring, and I can't say I was ever bored watching a Goldberg match. Not a 'great' wrestler by any means, but not as bad or limited as people make him out to be. The Lesnar match shouldn't count against him; both he and Brock were feeling unmotivated because of the crowd reactions and so didn't feel like putting on the best match. The problem with that match was that they stalled and barely had a match at all, not that what they had just bored everyone the whole time. The Bret Hart thing was a freak accident; I've watched it in slow mo and it looks like the normal kick. I've seen other kicks (from people like HBK) that looked and sounded a lot realer than that one did. I wouldn't hold it against him.
