...you could read his career and see:
"guy who could jam hitters and keep it on the ground when his velo was respectable - loses velo but his walk rate doesn't improve to compensate for one year...plus he's injured part of that time...then he takes a giant step forward in command and has his late peak...then he stops being able to locate as well as his body ages"
I think you're seeing what you want to see here...you're fixated on velocity and not seeing that it could be two different processes at work.
