Hitters. Make sure the coach you're following and taking info from is a hitting coach, not an exit velocity coach. There are a couple out there. *I know one openly admits it privately but won’t come out and say it publicly* When you're an exit velocity coach, that's your only goal. And sometimes it really is needed to raise a hitter's potential. But when it's the only goal, you forget there's a give and take to everything. Reckless. Make sure it doesn't hinder your ability to hit both sides of the plate, both sides of the field, and multiple speeds. (Not just one pitch, one speed.) THAT IS THE MAIN GOAL. To get hits, score runs, and win games.
