I've said this a few times now and as time goes on I'm becoming more conviced but I'm wondering if other people sense this. I think Murray has a physical problem. He lacks the natural strength to compete consistently enough to be at the very top of the game Sure he is extremely talented and successful by most players standards but has to work his butt off, more than others, to attain the strength and fitness required. He suffers disproportionately from sore joints and has a knee disability. I think he has the talent to win multiple slams but I just don't think his body is up to it. People complain that he is a pusher and should play more aggresively but I believe he is not physically able to. Not consistently anyway. I feel sorry for him because I think, deep down, he knows that this is the case and it fills him with self doubt and frustration and may explain the grumpiness and self harming, shouting at grass type of behaviour on court. And keeping the self doubt at bay by C'moning to himself. Last night he just looked so bloody miserable. What do you think? I think it would explain a lot. No Murray hating brainless comments please. Think logically about what's being said. Murray is a wonderful player there is no doubt but is his body capable?
