You're either missing the point, or choosing to ignore it.
Owner A checks in every four hours during coach hiring, revises his outstanding offers, makes new offers, etc. for his minor league coaches. He ends up hiring a 53 rated coach in Low A.
Owner B basically ignores coach hiring. He ends up auto-hiring a 52 rated coach in Low A.
Owner A's dilligence ends up for naught as there is virtually no difference between his hire and B's hire.
Now, are ****** coaches good for the development of players? Of course not. But "rewarding" lazy or inattentive owners by giving them the same (or close to same) results as dilligent owners is dumbing down the game. Which a lot of people are opposed to.
