Just for the purposes of discussion, I'll rank my top 30 (I probably weight ceiling more than any other single factor) and include tiers. I do not consider Olivera, Folty, Wisler, or Banuelos to be true prospects anymore.
Tier 1
1. Sean Newcomb - pretty much has to go here, has a chance to be up quickly
2. Ozhaino Albies - saw him once in person and that's all I needed
3. Kolby Allard - probably the best pure talent in the system
4. Lucas Sims - I was down on him, but he looks phenomenal right now
5. Austin Riley - another good year from being a top-30 guy overall
6. Touki Toussaint - needs better consistency, but massive ceiling
Tier 2
7. Max Fried - tons of talent but will obviously have to prove it this year
8. Mallex Smith - lower ceiling than some, but can provide real value right away
9. Braxton Davidson - crazy that he's now this low; great approach, just needs the power to come on
10. Mike Soroka - could fly up lists this year
11. Chris Ellis - don't know much about him; seems solid, this is about where most have him
12. Tyrell Jenkins - again, crazy that he's this low now; still can be a good 2-3 starter in the majors
Tier 3
13. Rio Ruiz - had a bad year at 21 in AA, it happens; one bad year away from dropping off completely; one good year from flying back up
14. Zach Bird - has the talent, needs to cut the walks down
15. Dustin Peterson - maybe too high, but flashed real talent last year, just needs to be healthy and consistent
16. John Gant - shockingly good after the trade last year
17. Ronald Acuna - like several others, a good year away from flying up lists
18. Lucas Herbert - just need to see him more
19. Juan Yepez - hit really well last year, may be underrated here
20. Ricardo Sanchez - this ranking shows the depth of the system perhaps more than any other; people forget he was 18 last year
Tier 4
21. Connor Lien - tough AFL, but still could be in Atlanta before long
22. Andrew Thurman - good in A+, really bad in AA; still has a chance
23. Josh Graham
24. Dan Winkler
25. Isranel Wilson - huge power, really intriguing
26. Derian Cruz - obviously an unknown now, good reputation
27. Randy Ventura
28. Luke Dykstra
29. Kyle Kinman
30. Christian Pache
