It is pretty personal. Some great hitters believe in doing everything the same way. Some great hitters believe in using the box to their advantage. It was made 6 feet long for a reason.
If a guy throws absolute gas, whats wrong with making him throw it 63 feet instead of 59. That may help some hitters with read and reaction time. With a guy like Wakefield, I would think some would be on the front line, but as I think, its very personal.
