Actually it depends, from a pure starting strength standpoint in a low squat such as experienced by linemen in football and sprinters (sort of in the sprint start) a low squat routine is needed. Often for sprinters, IMHO it’s only needed early in acceleration development when you are still developing acceleration at less than 20m on a regular basis. As for Football linemen, it would need to be targeted more often in overall training. I prefer 1/2 and 1/4 squats mostly as the overall strength of the muscles at the particular muscles lengths involved in maximal velocity in sprinting, the jump plant/take off in jumping, and block/release in throwing are often worked through even less ROM than 1/2 and 1/4 squats. You have to remember you are not training powerlifters, but athletes whose particular demands at certain events/tasks cannot be specifically worked in the weight room. If you are doing parallel squats that is typically enough for athletic development.
