They all do something I think is pretty smart. They keep there post leg bent for a long time and right before plant they rotate it down and in with the post/back leg.

They all rotate the leg down and in before land my questions are:
Would it be safe for a pitcher to try to turn the leg down and in like that into plant?
Is it a cause or a result to have the leg turn down and in like that?
