He has great wheels, I'll give him that, but on the side poses his arms look like twigs and his back, arms and delts are way small for his wheels 
His delts and arms need SERIOUS MASS, I hope he brings them up, then might place in the money 
I'll start by saying that Mark has, IMHO, the best looking physique right now (he's the Lee Labrada of the current generation). Lee Priest is my favorite BBer, but Mark has my favorite body.
With that out of the way, I'm not really argueing about your assessement, however I will say that you are hard to follow. In a previous post you said in reference to Anthony Catanzaro:
"I reckon he'd place 8th at the O, due to his symmetry, beauty, genetics, nice midsection, shape and aesthicism"
How can you say that AC would place top 8th at the "O" (by the way, to qualify for the "O" you must place top 3 at a Pro Show or top 6 at the Arnold) and that Mark would not be good enough to qualify for the "O"? Mark has MUCH more muscle mass than AC. His symmetry, aesthetics and shape are at least as good as AC... his midsection is much better, his conditioning is much much better and beauty is not a factor in bodybuilding (e.g. Dorian, Marcus for example). Not to mention the total lack of lower body on AC.
So I'll ask the question: How can you say that AC would not only be good enough to qualify for the "O" but to also place in the top 8, while Mark (who is vastly superior) would not even be good enough to qualify? Please explain to me where is the logic in that?
