Wow. I've never seen the Pirates' management hierarchy explained so clearly:
Littlefield decides what to do with the money allotted to him. The major-league payroll and development money -- not the same thing, necessarily -- are placed in his hands. Thus, if you have a complaint -- as so many do -- about why so much more of it goes toward one-year rentals rather than building up a sound developmental system, this is where to aim it.
Wow. So it's Littlefield's fault.
