John Cena's pretty good, just for having a really cool walk in song and sequence.
Now I'm not a big wrestling fan, just because it can be pretty boring sometimes and in my experience, a lot of the wrestlers just aren't very good anymore, but that is a pretty awesome shirt and I do like Cena whenever I actually see him fight. He's not a very good fighter in that, he's not the greatest at making the match look like a logical fight. He does a lot of the overly long and overly fake looking recoveries that seem to be a staple amoungst way too many wrestlers now and are pretty much the main reason I hate wrestling now and have for a long time. But that said, his actual moves are well crafted, look cool, and he seems like he must practice them 100s of times daily because he always does them very smoothly with the exact same timing every time no matter the size or shape of the opponent. In fact, that is almost an other detractor to him, his moves look too much like he's riding a bike the whole time and as a result don't look very impactful sometimes. Moves can sometimes look better when they look a little more laboured.
Honestly, the last wrestler I ever saw on RAW that I really liked was Mohammed Hassem. He may have just been an Iron Sheik rip off and his persona was completely inappropriate and retarded, but he was a damn fine wrestler. None of his moves were that flashy and he only had about 4 of them anyway, but they were all fast as fuck and as a result came off looking very real. In addition to that, his overall ring presence was a lot better than say John Cena's as mentioned above. Mohammed really looked like he was actually fighting and trying to win. Whenever he was hit with a move, he always looked adaquetly hurt but he never let it go on too long. He would always recompose himself in just the right amount of time to make it look like he was actually some sort of fighter in a ring, something that very few current wrestlers seem capable of doing for whatever reason.
I even liked his whole claim to fame that he was essentially undefeated since he never lost a fight due to being pinned or made to submit.
