That is partly my worry with guys who seem to develop "out of nowhere" - the Brewers have done an excellent job of maximizing players/pitchers, almost to a fault. Partly due to league changes (players in and out much faster than like the '80s/'90s), partly age (trying to obtain players in the 23-28 yo window), and partly due to the organizational approach of maximizing the talents, many do not have sustained success, but a lot of them have their best years with the Brewers. Lauer is the pitcher who gives me that PTSD when I try to dream big. That's maybe why I made that post as I am starting to like what Priester gives.
And to @sveumrules - right different styles of pitchers. And Lauer's success really happened with an increase in velocity which led to more K, and he was a fly ball pitcher. I think he never got that velocity back and that was one of the primary reasons he really fell back down hard if I remember correctly. Priester doesn't' rely on the K, but also may rely on grounders and elite defense.
