You know. I was probably wrong. I imagine they drill ....drill ....drill...... Along with going over high level tactics.
Some of my old friends are college coaches, and when I talk to them about what and how they coach, they are talking about things I never would have even considered. I remember one discussion about leading off, and positioning. They covered depth perception and how to either make your lead look longer or shorter by how much closer or further away a runner would be to the plate, and why at certain times you would want to change this. Really indepth stuff. But I'm sure they still drill taking off for a steal quite a bit too and other basic stuff.
