Sorry it's a big quote but it all seemed relevant to the conversation.
Wait, like the technology was flawed and now it’s more accurate (completely understandable) but are you also saying pitchers may have thrown harder in the 80’s than measured? Honestly curious and unsure of your meaning.
Agreed, but at the respective time. I am so hoping that in 10 years they will be writing an Astroball type book on this organization from this rebuild.
