I don't know about some of these guys, but who I do know:
Jeff Baker - will be blocked by Stewart so may have to move to a corner OF, or 1B when Helton leaves, but has value as long as he's in Coors.
Billy Butler - I like this guy, dude can flat out rake. The best prospect you have other than that Delmon fella.
Robinson Cano - if he wasn't in NY he'd be slightly above average.
Jason Dubois - could surprise if given regular PT, albeit old for a prospect.
JJ Hardy - Won't provide much with the bat
Chris Lambert - BC product should develop into a decent #3
Chris Lubanski - He finished the season on fire, if you're forced to have 2 Royals, you have the 2 right ones
Brian McCann - Better C prospect than Estrada who blocks him
Kendry Morales - As with all international prospects, hard to gauge, but he had some good numbers in his first season
Dioner Navarro - another overrated former Yankee
Felix Pie - it's a good thing he injured his ankle because he's not ready, but he will be in a couple years. Keep him.
John Van Benschoten - isn't he coming off Tommy John? Was rated better than Duke by some headed into 2004, so keep an eye on him.
Adam Wainwright - I think Lambert will eventually pass him, but he could be decent.
Rickie Weeks - My honest opinion is he's overrated...I see a .260 hitter with good speed and occasional pop. I would try to trade him for someone like Liriano.
Delmon Young - makes this team worth it.
In 5/6 years, that Young/Butler/Pie/Morales outfield could be the best in your league. Pretty thin on pitching though. Not bad overall.
