I’m not really posting this to come down on either side of the Maddux argument, just an interesting article that provides some context. So if his typical range 1984 translates to 89-91 (topping out at 95) on a modern gun, and the average fastball in 2008 was 91.4, by 80s/90s standards his velocity was probably average to slightly above average assuming velocities have been steadily increasing over time in a similar manner as they did from 2008-2024.
