Do Control and BB/9 even matter?

I am offline only if this helps. I have two new pitchers that I acquired lately FS Graterol (Control = 79, BB/9 = 68) and Veteran Robb Nen (Control 77, BB/9 66).

Clearly Nen has less control and a lower BB/9, yet somehow when I throw perfect pitches Nen has a much smaller margin of error but Graterol will be all over the place!

Despite the obvious lack of user input importance in this year's game, why would this be the case unless these stats don't matter at all? You would logically think that Graterol who has the better control stats would have the better margin of error?

Even though the difference in stats is very small, they outcome when pitching is substantial and very frustrating!

Control? yes BBs?not so much

It would be nice if SDS explained why this is the case then! There is no way that Graterol, who has the higher control, should be so much wilder than Nen.

Pitch confidence overpowers both of those ratings
