Iâ€™m wondering if anyone can define â€œleg collapseâ€ for us? I hear it mentioned very often but it seems to me there may be a fine line between actual collapse and just a â€œflexionâ€ of the back leg prior to moving the hips toward the plate. Is that correct or should there be no â€œflexionâ€ whatsoever by the back leg prior to moving the hips forward?
It looks like a lot of the pro pitchers Iâ€™ve watched on some of Dickâ€™s videos â€œdoâ€ have some flexion or slight collapse in their delivery.
If someone could explain exactly what the back leg should ideally be doing prior to the hips moving forward It may clear up this confusion for us.
I notice this tends to be a really confusing concept for most, and I can honestly see why. It’s taken me literally months to understand it because mentally it just wasn’t making sense or clicking. Basically to put it so it’s easier to understand: If the pitcher is moving “too slow” going into knee lift he’ll end up sitting over the back leg TOO LONG thus causing all that energy to be lost therefore potentially costing us velocity. Now if the pitcher moves quicker, he won’t have time to do much “collapsing”…Of course there will be some “flex” to the back leg…It’s when you have TOO MUCH flex which is a result of simply moving TOO SLOW. So YES flex the back leg but just be sure you’re moving quickly or you’ll end up flexing too much and therefore “collapsing”. Best of luck to you.
Collapsing the back leg occurs when the leg continues to bend after hand break. It must stop bending and stabilize so that the pitcher is able to move his body sideways once weight shift and hand break occurs. If the back leg continues to bend then forces are not going toward the plate but are going into the ground.
Optimum bend might be in the range of 30-40 degrees.
Collapsing does not mean that the leg does not bend or bends too much. It means it continues to bend too long. Nolan Ryan and Tim Lincecum got their bodies low so they bent their back legs more than most but they did not collapse.
For young kids who lack stabilization strength of the back hip, the best solution is to have them move faster away from the rubber.
Swinging the leg out and around or leaning back or forward can cause collapsing.
Great explanation Dick. That really cleared up my confusion. Now it’s a matter of having you evaluate Chris’ video to determine if he is in fact getting too low and collapsing.
