I teach a firm front leg. Not necessarily locked, but firm. You don't want the leg bent because it will allow you to lunge, lean forward or do other things that are not conducive to good hitting.
Best way to think of it is you want to drive *into* your front leg rather than over it. That requires the leg to be firm.
Ken, MY personal believe/instruction is to lock out / firm leg is a good way to say it. Interesting though as Samatha Findley, Callahan and Jessica Mendoza all seem to come into contact with a bent front leg, yet Crystal Bustos, Caitlin B along with the ones you sent, all lock on contact. I use DVDs of TIVOED successful DIV1 players locking out during classroom time, THOUGH just as many very good hitters do have bent legs.
Findley is a GREAT EXAMPLE of what I would NOT teach, but she was VERY SUCCESSFUL and how could I argue that!??? She bends her front knee AND DROPS her Back foot 10-12 inches as she rotates!!!!!!!!!
** I've mentioned before and I believe it more and more....
1) I can find video of great players with opposing mechanics, yet both styles are successful!
2) If an athlete practices enough (with reasonable mechanics), they learn to coordinate a skill that works for them. *** KEY is practicing enough reps at GAME speed and game stressors!!!!!
I'm beginning to back off telling batters they SHOULD do this or they SHOULD do that. I'm at the stage now to analyze what is NOT working and trying to help the athletes (batters in this case) understand that when they are doing something that pulls their eyes, over-extends-pulling them off balance, or anything that seems to be obvious to hindering coordination.
Who is right? Outfielder catchinig a ball on GLOVE shoulder or Throwing hand shoulder? Arguements AGAINST both, yet 50/50 when I ask DIV1 coaches what they prefer!!!!!!
Who is right? Cheri Kemp, Michele Smith and Cindy Bristow (OUTSTANDING Pitchers and pitching coaches) state Pitchers should NOT Open/Close hips for very valid reasons. YET Ernie Parker (also World renowned) teaches as many great pitchers in previous years do - OPEN/CLOSE!
I do appreciate the arguements for both. I also agree that MANY times in the last bunch of years I hear coaches COMPLICATE what they are saying with so much scientific/physics based rationale, that they lose the message, which means they are NOT effective in teaching. They COULD be correct, but many times the girls are more confused, so they get to a point of IGNORING that instruction as well as any instruction following, cause they lose confidence in the coaches ability to teach.
