Dawg,
I don't mind the questioning, but I'm not sure that I'm intentional enough with all my setup to answer your questions without guessing.
As I said in my first post, one thought I've held (when in B) is to let the ball turn my chest to 2B during the throw. Because of that, I'd say I'm not getting my eyes to the mesh point (base/glove/runner) very much earlier than the ball is arriving. If the throw is hosing the runner by a step or two, I'm golden. Or if a track star R1 is already there, I'm solid. I'm thinking if a runner is already in his slide but not yet to the base are the ones that are really biting me. The more we talk about this, the more clear it seems that I need to try to turn earlier after I confirm a good throw from F2.
As for footwork during the course of the play, I don't think I move much from B, but I do know that I try to move a step or two directly towards the base: closer to the throw (line between plate and 2B and deeper towards the base.) The footwork for achieving that is a guess, but I can say with confidence that I get locked down and do not make many calls while moving. If anything, I'm not gaining enough ground toward the call from wherever I start the play. I'm going to try to find some games I have recorded plus be more mindful of how I am executing this with my body movement.
Thanks for the replies, gentlemen.
