It takes a lot of control to throw those. From seeing Rochard a fair amount, I haven't seen her throw all of those but I'm sure she probably has them to some extent (you always have favorite pitches). It's good that she has a lot of options. Some days your curve isn't working so you need a slider etc.

Biggest thing is to be able to change planes. Typically fastball, curve, slider change (unless it drops) are all on same plane so you have to be able to make the ball go up and down too hence the rise and drop.

Oh and 2 knuckle drop is a different pitch than drop. The ball moves a lot different.
