While I want Chico to succeed, I find it troublesome that he is eighth on the list but has a shot to make our starting rotation this year.
There's a difference between the overall rating a prospect recieves, which is basically an upside projection, versus how ready they are now for MLB. They may have Chico projected to be nearly ready now, but not having potential for being a #1 starter. On the other hand, we may have a 17 year old who is years away from making MLB, but has tremendous potential due to being able to throw 100 mph, as an example.
Baseball prospectus has a assessment they call "gap", for how big the gap is between where they are now and being able to play in the majors.
