Howard, I completely agree on the fence drill and have been reading your recent writings with great interest -- I even bought a piece of rope yesterday -- though I'm not taping fingers together on their grips yet ; >
That said, I did use the fence drill for a young group of girls we're just starting to teach the MLB pattern swing to -- just one time and with a slow-mo swing just to get them to begin to understand rotation. They don't believe it's possible and when they see it is rotation starts to sink in a bit. It's not something I'd want to do 50 swings in warmups if I had a D1 team, but I felt it started to help them feel some basic swing concepts they'd never thought about before. Maybe I'm wrong : >
That said, what do you think about slow-mo swings with a back-foot to a wall or net to get them to feel 45 degree bat angle and inside hands and hips leading shoulder rotation versus dropping the barrel and bat drag? Obviously, if they drop or drag-load they hit the net and feel that reinforcement. Again, just to get them to start feeling and thinking about their swings in new ways?
I did not tape the fingers together...I put saran wrap on one finger, the index finger so they put the bat handle just in front of it and not in the back of the hand.
