But that's my point, right now Gowdy is all projection, with pitchers, that is more uncertain that with hitters. Pitchers seem to have a higher failure rate, look at Biddle, Savery, Gueller, etc., but also more come out of nowhere (master an offspeed pitch, fill out your frame and add 2-3 MPH, tweak your mechanics and develop command).
Kilome is a good example, two years ago hardly on the radar, last year I had him a 7th, this year at 4th.
First he added velocity, then he pitched a full season and showed dramatic improvement.
The odds of him eventually succeeding went way up in two seasons.
I have Gowdy at 27, and Irvin at 33, although Irvin pitched enough to have more confidence in him, Gowdy has more potential. If Gowdy starts 15 games or so and pitches a 100 innings this summer, depending on what he shows, he's a good bet to be in my top 20, if he then goes to Lakewood and starts 20+ gamed and shows increased velociity, top 10, if he dominates, top 5. But right now I'm just not sure about him, a lot of guys in the later part of the 1st rd aren't much different than 1S and early 2nd round guys, more projection than what you see in pitchers in the top 10. And I'm wary of projection - sometimes guys grow into their bodies, sometimes they're just bigger guys who throw the same stuff.
It's not just pitchers, I didn't rate Ortiz highly last year, they paid a lot of money but could he run (play OF), could he hit, would he be another Pujols, power with mediocre hit skills. His GCL debut at 17 answered a lot of questions, doesn't guarantee success, but he didn't look overmatched like a long-term development project with the odds against him (which is what Pujols has proven to be).
It's just my philosophy, I value both potential and the probability of success, there's real value in a high probability (50%) utility IF who might give you 1 WAR off the bench for 3-4 years, compared to say a 5 WAR ceiling player with only a 10% chance of success. So guys in the high minors who produce have value due to their probability of succeeding, guys in the low minors with high potential (good scouting reports) due to their upside. The highest value prospects are those with high ceilings who show a high probability of reaching that ceiling through their minor league performance (dominating and rising quickly).
