Might wanna consider the styles of the offspeed pitchers who deployed their stuff to great success.
I don't know of many changeup-first pitchers who weren't students of the game with their little black books and their encyclopedic knowledge of all hitters they faced.
And I don't know of many forkballers who cared about the other guy - if they were on, the other guy could do whatever he darn well pleased and no good would come of it.
But I do like the idea. And I like the "we choose this pitch" by era. I assume the circle-change was the 90s? Maddux, Moyer, Glavine and Pedro would all tell you it helped them out...
