The best coaches in tennis today do not share one thing in common.
That would be far too simplistic an explanation.
While it is difficult to rank coaches in a scientific, objective manner, it is equally clear that there must be some sort of rational assessment upon which to rate them. Simply stating that a player is only as good as his coach is nice, but it's also trite and cliche. If that were true, only the top players' coaches would make the list, and for no other apparent reason.
So what should be considered?
Two facts stand out:
- Great coaches bring their charges to the very top of the game. That means either the No. 1 ranking or a Grand Slam title.
- In the absence of the above, a top coach takes a player that is struggling, despite possessing tremendous talent and potential, and yanks him up the ranking and result ladder to places he hasn't been able to bring himself.
Think Rocky and Mick of boxing lore.
Here is a list of current coaches who have accomplished one or both of the above.
