Philip there was quite a long gap between Andy breaking with Miles and taking on Ivan. While some people say he should have taken on Ivan sooner I'm not sure he was ready to and I think it probably did him good to do it on his own for a while. He had to learn for himself what he needed to do to make that final jump to the very top of the game.
I agree completely with this. I am convinced that the time Andy spent on his own, before Lendl came on to the scene, was good for him. If I recall correctly, Andy was on his own for the majority of last year, and he had his best year in the slams - up until this year that is, getting to the semi's or better in all of them. That's not bad.
I might have said this before, but I think Andy was right to take his time in making a decision about who was going to coach him after Miles. There was so much speculation on the subject. Everyone within tennis seemed to have an opinion, it must have been a big temptation to ake someone on, anyone, just to shut people up. However, Andy took his time, knowing that he was making an important decision for the future of his career. I think that was really mature. Then, when he did take Lendl on, everyone had an opinion about that, some saying it was an inspired chpice, others suggesting it would all go horribly wrong and would all be over within a week! I read somewhere that Lendl warned Andy when they first got together that everyone would have a view on it, that it would attract publicity and attention. He wasn't wrong, was he?
Looking back on that time on his own, I think it made Andy take responsibility for himself. I'm convinced it made him look at his game and decide what he wanted, which I think is good for anyone. However, I think it takes maturity to see that something else is needed, maybe some other input. Maybe he had reached a point where he was more prepared to listen, or maybe he had reached a point where he felt that he needed to do something about anything that was holding him back, possibly fear of failure, or not being good enough, for example.
I think Andy knows better than anyone how important the years between 24 and 28 or so, are for any player. It seems to me as if he knew that these are the years where he should be peaking, reaching his full potential, and he needed something to help him do that. Well, it seems as if he made the right choice.
The thing that fascinates me is that when Andy started working with Lendl, they both said that people should give them six to nine months before things clicked, or words to that effect. They weren't wrong lol.
