Let me lead this off by saying that prospect rankings are wacky. It’s nearly impossible to quantify players against each other in one organization, or one league, much less all of the minors. It’s unlikely that anyone can see enough of over 100 players across the country to make such a list happen.
That said, readers love lists. Love them. Seriously, if there was a way to cross-breed lists with cats, train them to dance to the running man with a keyboard list-cat playing music, and then apply snapchat filters so that all these list-cats had the dog-face filter on, It might distract people from Pokemon Go for six minutes.
