So much harder than it was a year ago, but here we go. 1)Gleyber:Above average tools across the board except for power and even that may end at a decent 15 per year. He has been pushed very hard so I'm not going to worry too much about a declining BB%. Not an immense ceiling, but a safe bet to be a regular as far as 19 year olds go. 2)Contreras:His explosion couldn't have come at a better time. Vastly improved K rate, climbing BB% and supposed 1.85 to 1.90 pop times. The only guy in the system I have no interest in moving and the Cubs opening day starting catcher in 2017. 3)Jiminez:Nice bounce back after a disappoint 2014. He had a surprisingly low 17.2K% despite prodigious power. For me he unquestionably holds the highest ceiling of all the position players. 4)McKinney:Great plate discipline and good contact skills. Likely relegated to a corner outfield position, his current 10-15HR pop needs to increase for him to be truly exciting. As is, I could see him becoming a David Dejesus type. 5)Happ:I'm going to try and no panic about the bad K rates at lower levels and focus on the better than advertised, power and speed. To go along with a nice BB%. I could see his ceiling as a 20/20 guy which would be a steal if he can stick at 2B or CF. 6)Almora: I'm buying on his improved BB% and power to go with his already elite contact skills. His 2nd half .301/.370/.464 line at AA was a resounding success for a player who will still be 21 when the 2016 season begins. 7)Underwood: Two potential plus pitches with a third that should be at least above average if he can locate it. 2016 will be big for him, because he needs to start showing he can miss some bats. 5.89K/9 isn't going to cut it. Still, the ceiling is substantial 8)Edwards: I'd like to see him spend the entirety of 2016 in a final effort to see if he has any hope of sticking as a starter. The stuff is filthy and his ability to not give up hard contact is otherworldly. Even if he doesn't stick, he's a closer in the making. 9)Cease: Supposedly touched 97-99 in just about all his starts coming off TJS. The control was a bit erratic but that was too be expected. Probably the highest ceiling for a pitcher in the sytem 10)Eddy: Not sure who to believe. One person talks about him like he's just another guy while another talks about him like he's a borderline top 50 talent in the minors. 11)Zagunis:Between the amazing plate discipline, strong arm, moderate power and speed, Zagunis should be able to find a niche as a 4th OFer. If the defense is good enough, I could even see 2nd team starter. 12)Pierce: Already 24, this is the year he has to show if he's going to be a starter going forward or if he's going to be relegated to the pen. The stuff is too good for the poor K rate 6.82K/9. If he does go to the pen I think he can be a strong set up man. 13)Steele: If we're talking about what is as opposed to what might be in the future, Steele has been well ahead of Cease and Sands. He doesn't have Dylan's upside, but he still has middle of the rotation stuff. 14)Candelario: Big bounce back year after nearly falling into the failed prospect abyss. It all depends on his ability to stick at 3B. Another year of his 2015 numbers with solid defense reviews and I'd have him safely in the top 10, but if he ends up at 1B I'm not sure I have him in my top 25. 15)Williams: By all reports the stuff is just so so and yet the guys finshes the season in AA after having not thrown above Short A ball before 2015. He may end up being the cheap answer to replace Hendricks once Hendricks gets to FA.
