Do you know that at one point Puerto Rico was exempt from the draft? When it was added to the draft we went a good long while without any impact players coming out of Puerto Rico.
Imagine you are an owner of a ML team. Does it make any difference to you if every team gets players out of the DR or if no team gets players out of the DR? I'm going to say it doesn't make a difference to you. As long as it even.
Imagine you are an owner of a ML team. Why pay for an academy if there is a draft? What's in it for you? Just draft 20 kids and slap on your DSL team.
Imagine you are a Buscone. Sure you are not a nice guy but a lot of kids would end up with nothing if it wasn't for your efforts. If there is draft you need to find a new line of work, no profit for you in a draft.
Imagine you are a young player. You know your whole family is depending on you. You are smart enough to know you probably won't make it, that this signing bonus is the ticket for you and your family. How would you like your free agency to be replaced with a draft position and a slot payment?
As a general guideline fans should be very suspicious of anything ownership pushes for. We know they are not concerned with player welfare.
