First, there is a philosophical debate going on here. After reading Bob Shaw and Mike Marshall, I have come to believe that a high release point is more important than releasing the ball closer to the plate. Roger (and Tom House) disagrees. At the end of the day it may not matter either way, since there are examples to back up both arguments.
Second, I will grant you that if you take a long stride, you do have to stride forward powerfully. That enables you to get more of your weight on your GS leg which allows your PAS foot to come free of the rubber which allows your hips to keep turning. If you don’t stride forward powerfully, you will end up basically doing the splits with your weight on both your GS and PAS legs. IOW, Roy Oswalt has to stride forward so quickly because he takes such a long stride.
Third, let’s talk about stride and weight distribution in the context of some photos of Nate Robertson from last night.
Photos 1 and 2 represent basically the same moment in time. The shoulders have turned about 60 degrees and the PAS upper arm has externally rotated 90 degrees. His PAS toe is off the ground in these photos because he has powerfully strode into his GS leg and his weight is on his GS leg as a result. Also notice that his PAS foot is laces down.
Photo 3 represents a slightly later point in time just before the release point. Because his weight is on his GS leg, his PAS foot is able to come off the rubber and his PAS knee is able to keep coming forward. This allows his hips to keep turning, which pulls his shoulders around.
