It is about time. MLB Teams spend millions on analytics, Players, facilities and other stuff and yet in the minor leagues they hire a former pro telling their hitters to get the foot down early and hit grounders to second (famous example because buxton who is a struggling top prospect said it).
That is slowly changing and many Teams already use more modern stuff but there are still Teams like that out there. That is just a huge hole of ineffectiveness, shouldn't really happen.
In pitching the analytics is a Little farther along the way than in hitting though, I think.
Rick Peterson is the furthest along with analysis. More are following his lead like Brian Bannister. There is also similar hitting analysis available.
But my original post was about going as far as tracking devices on the athletes bodies as they perform. In the case of the USA field hockey team it's tacking data that determines if their performance is falling off due to fatigue. It's tracking what is the optimal point for each athlete before their performance drops.
USA field hockey finished last in the 2012 Olympics. In four years of using this system they've risen to 5th in the world. They're 3-0 in pool play this week beating #2 and #3.
From what I've read (don't know the game well enough) it's not the talent is so much better. They're getting optimum performance from players and getting them out and rested before going back in.
I've noticed the kid from our neighborhood isn't on the field quite as much. They were relying on her too much and fatiguing her in the past.
