Re: Second half of season 2012.
I think I have to agree with both of you. PP is right, Marin is not young anymore and mental lapses are here to stay, there's not much he can do against those.
Misty is right, there's plenty time left for him to do something. I never believed that Marin will be multiple slam winner but I was always sure he'll get one. Lets say he has another 4 years at the top left, that's 16 slams and if he stays at the top 8, which I believed he will, he might get one.
He needs to do two things, find a new coach and improve serve motion.
