What's interesting in the above amalgamated list is three of the absolute best raw stuff guys in the system (all playing at Low-A Carolina) don't even make the list. All three struggled with control and consistency - hence, they remained in a Low-A placement by year's end. But, you'd be hard-pressed to find better pure stuff guys than RHP's Quinton Low, Jesus Rivero, and Yerlin Rodriguez. The problem there, however, is their control issues often overshadow everything else. Quite a bit more so than Shears who, as you astutely point out, never really succumbed to the wild pitches; the inability of his catchers to catch and frame his stuff consistently; etc. He found ways to work around all that and get punch outs or crucial timely outs. Low and Rivero, in particular, were prone to meltdown innings. Low completely lost himself in late summer and then closed his season on the 7-Day IL from August 11th onward. Rodriguez was as lights out a Low-A closer as you get during June and July but this is surrounded by volatility. I digress. All three of the these guys (Low, Rivero, and Rodriguez) have Big League raw 'stuff'. But, as of right now, they are very much lottery tickets. This is a huge off-season for their development.
Needless to say, performance aside, if I am in the player development part of an organization I likely take their raw tools from a strictly prospect and up-side perspective 7 days a week over our collective performance-based 'Honorable Mentions'. And, the addendum here as we know is none of that raw stuff matters if it can't find the zone or swings and misses consistently.
