This exchange was in the comments - and I was very surprised at the assessment of Maples' ceiling ..Marc Hulet says: Maples has the highest ceiling of any pitcher in the league and people I spoke to felt he would be ready to go for spring training 2013 so I’m excited to see what he can do. His ranking is based on pure potential and upside. I've heard that too, that his his breaking ball is exceptional and he's really fast. I agree with Hulet that he's easily got the highest ceiling of any of the pitchers, Paniagua included. But as Hulet said, it's just pure potential at present. As analogy, the Cubs paid Paniagua a serious bonus based on scouting and scouting alone. Other than struggling in a bad of Panamanian league last winter, Paniagua hadn't pitched in games in years, and he wasn't any good when he did. But his scouting stuff was plenty good. And now, 3.2 minor league innings, I personally think it's entirely appropriate to include him in a top-10 list. (6th on mine). Neither the bonus nor that valuation is based on his 3.2 innings; it's based on scouting and the 3.2 innings and whatever instrux stuff. I think it's entirely fair to rank a guy based on scouting and potential. While Hulett didn't rank Paniagua as high as I will, I think it's entirely legit for him to rank Maples very high, based on pure scouting and potential. Talent-wise, Maples's stuff is better than anybody we've had in the system since Archer, and his talent relative to his position is much more special than Vitters or Szczur or Villanueva or Hernandez. That he hasn't pitched much, does not change the scouting look of his stuff. I think guys like Hulett don't want to miss on prospects who might become special. I've got Maples 8th, because I'm a believer in control and the early results aren't favorable. I like his pure stuff better than for Paniagua, Johnson, or Underwood, but I've got him behind all three because he seems least likely to gain control. Still, if he's healthy and gets some coaching, pitchers can sometimes make adjustments. More common for a high-walk pitcher to drastically lower his walk-rate than for a hitter to drastically reduce his K-rate, even if still pretty improbable. I do agree with the argument about inconsistency on Hulett's part: if Maples is in based on scouting/potential, and Underwood, then Paniagua should make it too. All three are in my top 8. So if I am reading this right, you have Johnson, Paniagua, and Underwood all in your top 7? Interesting. Why them over Vogelbach or BJax? Do you think the pitchers upsides are that much greater than Vogelbach and BJax? Or Candelario? (I'm assuming you have the same top 4 as what seems to be the consensus)
