Agreed. In fact, even if he was "just an statistician", as he is a good one, it is a good addition. I guess people are underestimating some aspects of the game. Those guys play countless balls. There are a lot of useful statistics out there. In some cases it will mean less time on court against lesser players, which is already reason enough to hire one guy like that. Some times it could mean the difference between winning and losing against a good player -- just one of those in a year is a good enough reason.
Actually that's a job I would like to try myself, I am sure I would do it quite well (some other guys here on board too).
Agreed again (it is getting tiresome!). Just look at Ljubicic! He just got on guy who was candidate for GOAT and let him distinctly better! How hard do you guys think is that?
