Would anyone really miss it if you just removed coaching from the game completely? Just saying.

Real life. OK. The Angels just fired Mike Maddux. Far as I know, Mike Maddux has been one of the most universally respected PCs in the majors in the past 20 years. General consensus seems to be that there was basically nothing he could do with that staff.

So hell, just streamline player development and let the players duke it out on their own merits without overlaying this additional film of unknown and unprovable "refinement" which Coaching currently is.
