I would agree that according to Charlie that is likely the case. My statement was that the jump/run/drill circuit acts as a bridge to SE, which is, in a L-to-S program more removed from pure sprinting.
In general though, I view jumps work as sitting someplace between general strength (weights) and sprinting. I have gotten much better results when I have taken this approach. It is simply my opinion based not only on my experience and that of other coaches that I know and respect and not meant to argumentative.
