Re: time to hire up a coach?
It's not about blaming Mike, I'm sure he's giving the maximum he can and there's no questioning that he's 200% involved in his job as Maria's coach. That's not the problem.
It's about blaming Maria for not taking necessary steps to renew her tennis and more generally the perspective on her career. Maria and Mike are at a point where it's the same thing all over again; as a team they can't think out of the box anymore. Something external is needed to feed the system, otherwise it collapses. And IT IS already collapsing right now.
