It's my educated guess that Bloom makes most of the decisions on the big team's player acquisitions and dispositions, subject of course to the payroll budget imposed by Henry.
I'm sure Bloom receives a lot of information and opinions from others in the organization before making those decisions, but he has the final call.
You mentioned something you had read about Bloom being much more consultative than DD was, to the point that maybe Bloom considered the input of others too much. That aligns with the process I'm describing.
