This "pointing" is really just a moment in time. Again, the stills just don't show what's really happening. VIDEO VIDEO. This position you showed happens for an INSTANT!!! This pitching thing is a dynamic activity.
When do you point it and for how long? Show me all of the pros who are doing this and don't show me yet another still image for proof because I think I'll just tear my hair out.
Here's a list of MLB pitchers I checked VIDEO of on this issue and NONE of them "point" the glove. Even the ones who have the lead arm straightened out at some point "sweep" it rather than "point" it.
Clemens, Jimmy Key, Beckett, Verlander, Brown, Rivera, Nolan Ryan, Pedro, Prior, Randy Johnson, Oswalt, Schilling, Kazmir, Smoltz, Wagner, Reyes, Zito, Radke, Sabbathia, Benson, Colon, Schmidt, Santana, Sosa, Kinney, Wood, Lohse, Koufax, Palmer, Hawkins, Gibson, Seaver, Tim Hudson.
So, tell me, if these guys don't do what you are recommending as being so necessary in the people on this board you are advising, why should anyone? Why? All of this "theory", supported by still images, isn't supported by the pros.
