The advent of tools like HitTrax for measuring balls of the bat have revolutionized certain aspects of hitting instruction.
But there's a problem.
When I see the swings of these hitters discussed, two things are the main subject of discussion...
- Exit Velocity
- Launch Angle
...but one, in my experience critical, aspect of the swing is rarely, if ever discussed.
That means the time it takes the hitter to get from Start to Contact.
I know some systems measure this value, but I question the numbers these systems produce because I see too many people (supposedly) doing something that is actually very hard to do.
Stop thinking SPEED and start thinking ACCELERATION.
Stop thinking DISTANCE and start thinking TIME.
