Tips for Long-tossing and/or "Long-throwing"

I saw a great MLB Network Diamond Demo on long-tossing (2nd half of clip) or what Mitch Williams calls “long-throwing.”  I like and agree with his explanation on the difference in terminology.  In the Demo, Mitch mentions “walking into the throw.”   I have always prefered the method used by Roy Halladay in the following YouTube clip.  He takes a step forward with his left foot but then hops behind with his right foot, steps, and throws.  I like this better because it keeps the pitcher’s front side closed longer.  A good habit for a pitcher!

The next clip shows a long-tossing routine which includes what they call the “stretching out” phase and the “pulling down” phase.  Some people see value in launching a high arching ball to stretch out and strengthen the arm but, like Mitch Williams, I don’t like the idea of lifting the front side too much and leaning back to do it.  That’s not what pitchers do in a game so I’m reluctant to have pitchers do it in practice.  I believe there is more value in throwing balls that are able to get to your partner on a hard line drive rather than a high arching one that travels 300+ feet.  For most players, that might require maxing out at around 150-200 feet depending on your arm strength.  I guess that means I like their “pulling down” phase better.  

  
Over time, pitchers usually develop a long-tossing/long-throwing routine that works best for them.
