When I used to coach and train teenagers, that truth really does work. You can have an incredible and powerful squat, and not jump worth beans.
The best way to build strength for sprinting is to sprint a lot,... and supplement that with working out
If you goal is athletic.. play the sport as much as you can and supplement the athletics with the workout
There is still something to be said for training the muscle groups that you are going to be using the most often to help strengthen them and hopefully cut down on the potential for injury. It might not make you play the sport better right off the bat but not being injured helps you play the sport longer and get better at it.
