I don't devalue velocity, I just don't see it as the be all and end all.
Suarez is a much better pitcher than VV or Pivetta, although they throw 2 MPH faster on average.
Nola has been a top pitcher throwing 92-93, t95, not 94-96, t98.
Sure you want pitchers to throw harder, but only within their general progress, that is, not by focusing on velocity per se, but by physical training and tweaking and perfecting their mechanics. The purpose of getting stronger and building stamina is to throw harder without more effort, to build stamina and provide a foundation for pitching, not throwing.
For example, Falter would be much better off focusing on developing three pitches he can throw consistently and with command than spend the offseason trying to add another 1 MPH to his FB. Whether he throws 92 or 93 or 94, it's not fast enough to consistently get by ML hitters if he can't command it and keep hitters off balance by throwing a changeup and slider for strikes. Otherwise they'll just sit on that FB and spit on his other pitches.
Kennedy didn't lose that game b/c his FB is 94 instead of 96, he lost b/c his curveball broke waist high instead of diving below the knees.
