Like money, speed isn't everything, but it is certainly something! While hitters will catch up as mentioned, the decreased reaction time due to faster speeds is still nothing to sneeze at. Hitters 'catching up' to a pitcher lends to the effectiveness of a changeup...which in turn hinders them 'catching up' to the FB...
My DD throws a very deceptive and effective changeup as her best pitch. It is her CU that makes her FB 'good enough.' When we talk about how to improve the CU, increasing FB speed to accomplish this is always part of the conversation.
Yes, 'stuff' is good. A faster FB makes your 'stuff' pitches even more effective IMO.
