Kilome is strictly projected off velocity and a promising curve, his K rate is horrible for a top prospect and his BB% is bad, and he lacks a 3rd pitch.
He's 23 and running out of time. If he can't develop better command and a third pitch, he's at best a setup RP, which just isn't that valuable (Garcia).
I also think Medina is overrated, but he has more time to turn it around, and he's outperformed Kilome at the same age. Medina has a full repertoire, mastering that and improving command is far more valuable than 1-2 more MPH.
Our two best starters are Nola and Arrieta and both throw 92-93.
Eflin was our third best pitcher until his blister, and that was less due to velocity than improved command and secondary pitches. He added a MPH to his 4 and 2 seamer, but also sharpened his slider and curve. His next step is developing his changeup, do that and he has a shot at #1 starter.
