Quick story about velocity. My son was on his official visit to his D1 school. His team buddy was having breakfast with us. He stated matter-of-factly that, according to the pitching coach, velocity was only #4 in importance behind movement, location, and deception.
Surprised by this, I asked him "Are you sure?" Yes, that's exactly what coach had told him.
The next day we were having breakfast with both the pitching coach and the team buddy. "Hey coach," said the team buddy, "I told Bum Jr. exactly what you told me, that velocity is only #4 on the list which includes movement, location, and deception."
The coach looked at him blankly, paused, and then asked: "Did you tell him WHY velocity is only #4 on the list?"
"No..not sure what you mean."
"Because by the time you get here you better already have it."
