1-10 is mostly set. The bottom third is really hard to rank. You could replace some of those players with Maximo Castillo, Joey Murray, Logan Warmoth, Riley Adams, Harold Ramirez, Gabriel Moreno, Brock Lundquist, Alejandro Kirk, Otto Lopez, Cal Stevenson etc. It's a good problem to have when you have too many prospects that could rank in the Top 30.
Edit: Also Chavez Young as well. Our system is loaded.
