Already been said, but my main 2 guys would be Eric Hosmer and Jay Bruce. However, they are definitely high risk/high reward type players where they are currently being drafted because they both have poor plate discipline. Hosmer is a hacker who doesn't walk much, and Bruce K's a lot. However, both approaches can still have success in the BA category.
I look for Hosmer to be in that top 3 1B discussion because he can contribute double digit steals. I know his power might be capped because he hits too many GB last year, but he is going to need to hit 30 HR (or very close to it) if he wants to be in 1st/2nd round discussion as a 1B, but I'll take a leap and say he gets it.
Bruce's power has increased all 4 years in the majors, and he chipped in solid SB last year (albeit at a poor SB/CS rate). I think he takes that next leap this year and hits 40 HR (a very difficult task in the post-steroid era), steals 10+ bases and gets that avg over .280. Lofty projections, but that's what it will take to get into the 1st/2nd rd discussion since he doesn't have the potential to steal 30+ bases like the 1st/2nd round OF's like Braun, Kemp, etc.
The guy I really want to believe in is Jason Heyward. But he is really struggling with that new swing in spring training and looks like he could be 1 more year away (still very young). Since I don't own him anywhere, I hope he does struggle because he will be had VERY cheap midseason if he has under 15 HR by then.
If I had to pick a guy thats really far out there (ADP 186 on Yahoo), it would be Mike Moustakas. I'm surprised people are this low on this guy after struggling in his rookie year. I know he comes with his baggage, and most are capping his power potential this year at 20 HR, but if he can somehow reach his potential (keep in mind he was an elite prospect in the minors) this year and churn out a 30+ HR 100+ .290+ 8+ SB season, he will be in the 2nd round discussion next year at 3B since there are sooo many question marks at that position. Highly unlikely, but I'll take a shot in the dark.
