Some of the fanboy responses here are completely ridiculous.
- yes he should be fired because I love CM Punk
- no he shouldn't be fired because I hate CM Punk
That seems to be the gist of most of it here.
Should he be fired? No.
Is he an unsafe worker? Having never been in the ring with him, I can only surmise, but there's far too many examples of him not being safe to not believe this.
What Ryback needs to do is acknowledge that he isn't a safe worker, and that he does hurt his co-workers from time to time, and take the steps to improve and ensure that doesn't happen. It's really that simple.
When he tweets about Punk saying that he's sorry he's too fragile, and mocks Punks legitimate complaints about how much he hurt him in the ring with his toys... while funny for the marks, it says a lot about how Ryback simply doesn't get it. Guys should not be leaving the ring injured after working with him, and eventually if that doesn't change, it will catch up with him and either someones going to take it upon themselves to teach him that lesson the hard way, or management is going to decide that he's too much of a liability and let him go.
Listen, accidents happen and guys do get hurt while wrestling. The sport may be a work, but it's a very physical work. The trick is when it happens during one of your matches, to make sure that it actually is an accident, and it wasn't because you are sloppy, you just get caught up in the moment and don't realize what you're doing, or you simply don't know what you can and cannot do with a particular guy.
That Steamboat video is a perfect example. Here's a guy who had to retire about 15 years earlier because of neck problems. Knowing Steamboat, I'm sure that even with that, he knew exactly how to take that clothesline and not get hurt doing it. There was a lot of fail there. It's not all on Ryback, but he does deserve blame. They limited Steamboats ability to take the clothesline properly the way they pushed him into it... which I'm sure was done to add a sense of realism and show how brutal the Nexus was. Understanding the situation though on Ryback's end, he could have easily let up on that clothesline and left it up to Steamboat to control how he took it, instead of just hitting him with a legit, hard clothesline. Working with a guy like Steamboat, he could have made that look just as good without ever feeling a thing. And if Steamboat says that he can't do that bump and make it look as good... then you simply work out another way to get the angle over where no one does get hurt.
If Ryback is hurting guys consistently, and does continue to hurt guys without ever understanding that he shouldn't be doing that... then he's nothing but a mark in tights.
