The "trainers" get a flat percentage cut that's unchanging. If the Sox spent 900 K on his players, regardless of the actual allocation, his earnings do not fluctuate. He engages in the practice because of future benefits (i.e, the team signing players that may go unsigned), and overall strength of the business relationship (pleasing a team that guarantees him future paychecks). Most teams that have a dedicated academy here (The D-Backs immediately jump to mind) heavily engage in this business practice. But they're not doing this s*** in the open. Someone with ties to the baseball world theorized to me that the Sox got caught because they got sloppy in their handling of these negotiations when the change in the cusp of baseball operations was imminent. That may have played a factor in their recklessness. Per his recollection, The Sox/Ben/DD change/power struggle was quite a saga, and it was pretty messy. Stuff the fans aren't privy to, he said.
