I am not advocating everyone try to race down the mound at the speed of light, however I find it very interesting that many very notable / successful pitching instructors will get pitchers moving faster, to clean up mechanical flaws (less goes wrong if your tempo picks up), rather than working on mechanical flaws first then tempo. IMO - too many pitching instructors are looking at still video clips, and teaching "positions" rather than looking at the dynamic movements that create the positions...whereby they take "non-teach results or by-products" and try to make them into teachable positions / mechanics. Case in point, if you have a pitcher that is having a problem activating his hips prior to FFS, the last thing I would do is put them in a static position with his hips square to HP, and his shoulders back. Instead, you look at what is happening before the desired result.
