A Legitimate Question

Why did they play Volpe over Jose Caballero in the playoffs?

Aside from saying that Brian and Boone are incompetent morons. That's a given. I'm trying to get my head around their thinking from a financial standpoint because, as we all know, the bottom line for the Yankees is the Bottom Line. 

Volpe was hurt and they knew it, even if they did not understand the severity of it. That said, clearly he was a lesser version of a player who was already a lesser version of his "potential".  

Despite this they played a hurt guy over his superior replacement during the playoffs. 

Why? 

I get playing him all year if he's your guy but, and I'm talking financially here, doesn't Hal make more money if the team advances?  

Once the Yankees get past the trade deadline that's all the money they are going to spend on players for the year. So, financially, isn't the next goal to maximize their value? 

You know, WIN? 

Advancing in the playoffs means both additional attendance and TV revenue. Beyond that, the Yankees get to live live off of the "Historical Value" of a championship team.  Bobble heads, caps, jerseys, bringing them all back for a "special day" etc. 

So again, this isn't about an owner and a GM not bringing in the pieces to win, that's a separate issue, this is about failing to put your best team on the field from the players you already have. 

It doesn't make sense... financially.  

It doesn't even effect Volpe's value long term because the team could just say the benching was due to injury and the surgery in the off season backs that up. 

So for the last time... why?  What could possibly be the reasoning?
