Yes, I misinterpreted his statement. However, aside from the differences between maximal and operational outputs, I would say players reach their highest operational speeds more often than people think in Football. Also, in consideration of the varying levels of athletes, only elite ethletes are entering maxV at or around 60 meters. The vast majority of athletes that most of us will deal with enter it much sooner, making it that much more important to develop. Most high school athletes will have reached their top speed by 30 yards, college slightly further, and NFL further as well.
I agree with what you are saying I just thought it was important to point out these differences.
