text: I think he may be talking about illegal pitches, where the trailing foot of a pitcher must remain in contact with the ground until after the ball is released. The umpires rarely watch for this unless an opposing coach complains. Even then, the umps often cannot see it in real time. Some of the "best" pitchers gain a mechanical advantage by leaving the ground before releasing the ball and are simply allowed to do it. Other pitchers get called for it, which awards a base to the batter and all runners. White, having been an elite pitcher, can spot pitchers who leave the ground and often asks the umps to call it. Opposing coaches probably hate him for it. The fact is, the rule exists for a reason, but it is enforced rarely and unevenly, which is bad for the game. White makes a good point.
