Batista dropped Cena behid him ate the punch then looked back to make sure Cena moved before bumping. It would've been a bigger "botch" had he bumped without looking and cracked heads with Cena.
The biggest challenge for Ryback is that todays audience expects good to great matches from ppv main events they've been condition to expect this since the early 90's. Ryback may devlop into a good power match wrestler, but he has a looooooooooooooong way to go before he's ready for the typical WWE style 20+ minute ppv main events. They may be able to change it up some if he gets over enough but I don't think people shelling out 50$ for a ppv want to see 5 minute matches headlining.
I can see why people like him, but from what I've seen he looks dreadful.
Alright your first defense for Batista in what I believe was the bump botch is pretty pitiful, no offense. He could have taken the bump from Mark Henry and landed flat on his back rather than backpeddling all the way across the mat and then falling over. Batist was hamming it up.
The next bit, I won't lie, he needs to work on his cardio. We know he's strong enough to do whatever he needs to do but without the ability to work longer matches he won't go anywhere. He's got the charisma to get his catchphrase over and connect with the crowd, he's got a gimmick that most guys in his position wish they would have debuted with, all that is left is to work on his cardio so he can work more impressive matches - and really, it's not impossible to fix that.
However I disagree, Professional Wrestling is less about the individual prowess of individual wrestlers and more about chemistry in the ring and how compelling the two can make the match seem. Hell, you don't even need to show your actual skill when you have a snappy catchphrase like Daniel Bryan. No offense, the guy IS good imo, however he rarely shows anything but kicks and a submission maneuver or two. You see more variety with CM Punk and he has to get over with Mic Skills and mat work alone and people will STILL shit all over him on this board.
Ryback's work isn't atrocious, he just hasn't adapted completely. He's forced to work house matches with the same three or so jobbers when he needs to work on his stamina and how to handle bigger opponents. Honestly for me, Ryback would be the only thing that would tempt me to actually buy a PPV, not 100% though since PPVs always look lackluster from the spoilers.
So in short, Ryback needs a good deal of work so that he can eventually make a credible and compelling main eventer in around 4-8 months, creative needs to give him some credible opponents to work on till then, and maybe cut a promo or two. But even best case scenario, even if he proves able to move well in the ring for 15 minute matches and execute moves superbly, a good chunk of assholes online will find room to bitch.
I mean, they already call Damien Sandow over rated and a rip off, I'm sure Dean Ambrose is a shoo in for the same treatment.
