The Padres system is one that a lot of people are find hard to understand. Grady Fuson, the person in charge of their draft, has done a good but not great job in the last 2 years of assembling talent that often goes overlooked by fantasy fans. Here's some thoughts on their prospects that I have had recently:
Cedric Hunter: A year ago, he was their best prospect, as ranked by Bsaeball America, but has since been kind of overtaken by Headley and Antonelli. still, he's their 3rd best positional prospect, and while he profiles as a solid but unspectacular CF, he won't steal 40, or hit 40, but what he would be is a guy like Melky Cabrera, however, I really think he profiles as a better overall hitter than Melky, with more pop and better defense.
Matt Latos : Signed as one of the last draft and follows, his makeup is the only question that burdens him. Armed with a 95+ Mph fastball and a funky curvish breaking pitch that lacks consistency at this point, Latos needs minor mechanical adjustments for it to be considered a plus pitch. If he stays in the bullpen, he could be up as soon as 2009, but if they keep him as a starter, it will push his debut back until probably late '09, or 2010 so he can iron ou the wrinkles on his newest offering, the straight change, and improve his durability. Overall, though, he is what I would call a top of the rotation arm, but the liklihood he stays in the rotation is only at 25-30%.
Kyle Blanks - A huge speciman at 6'6 and 280 lbs., the 21 year old Blanks is still a project despite hitting .301/.380/.540 for a .930 OPS last year. He's suspectible to hard inside stuff, but he still has a nice power profile and is their best power prospect.
These are a few of the padres prospects you may have heard of, and while their systemis a bit unconventional in that they seem to go after the Brad Chalk's and Kellen Kulbacki's of the world, I thiunk they have a lot of impact arms, including guys like Schmidt, who although he had surgery is still a guy that profiles as a #3 starter because of his southpaw arm, his competitiveness, and his plus ancillary pitches. Drew Miller is a bit of a wold card, a guy who could be a top of the rotation guy, but a couple of things have to fall into place for that to happen, and as such, becomes more likely to become a #3-#4 starter for the Padres.
I hope thi shelps, and let me know fo you have any other questions about specific guys.
