There's fault to be found throughout the organization. I really think @DocBauermade some great points.
IMO, ownership and whoever is in charge of TV contracts/budgets is chiefly to blame for starting the perfect storm. Thier ineptitude trickled down and infected the players in the end.
Here's my question: If the players are ultimately to blame, who let that happen? Who's "managing" them? Who's influencing their thoughts and actions? Who's motivating them? Who's theorizing 2-strike approach with them? Who's reinforcing fundamentals? We hear about C4's leadership and Farmer's team meetings. This is great but why is it necessary? What is lacking? Who's running this team? If it's not Rocco's job, who's is it? The bench coach? Hitting coach? I believe this young, talented team was shorted the management they deserved.
In-game management is another area of weakness I won't expound upon.
