Yeah I think this is kind of why they've been reducing the number of rounds over the years (and this last year reducing the number of minor league teams overall). Too much filler in the minors and a lot of it is just a waste of time and money (For both sides really, it's not like the low minors players get paid much anyway). The whole point this comes back to is there is a lot of freely available talent, sure it's nice to say we got something for a guy like McKinney or Knebal but really you're not actually gaining anything of value when there's an unlimited number of lottery tickets playing in the low minors, or independent ball, or 16 year old Dominicans, etc that can be had for virtually nothing and are realistically just roster filler.
