Yes I have to agree with this. I would also add that Novak's physic in many ways means that he's always been walking a tightrope. If injuries start to become a factor he could find it very hard to get back to the top. I hope that's not the case, but it's a risk.
Also, regarding the personal issues he mentioned. Has anyone seen the clip of his wife giving him a blast for not saying thank you for her filming him for his facebook fans? Wow! Sounds like she wears the pants in that relationship so maybe he has a bit of stress at home
it's amazing how people point to this video as if it shows there are personal problems. Has anyone here had a girl friend of wife where they never fought about anything ever? what we see in that video is what normal people do pretty much every other week in a relationship.
