You have a bunch of guys that are all about the same value. Jennings may be a good choice because of the 40 SB potential, but his avg will hurt. Lawrie is young and at a somewhat shallow position. RA would be an easy choice if he did not move to the AL East. Hosmer should start to produce real soon, but is it this year. Moore will be a front end starter but it may be in 14' or 15'. With all that BS, I would go... Stanton Lawrie - Nice lineup around him, he's slotted to bat 5. Jennings - Batting leadoff.
Rationale: Lawrie has 20/20 potential and I think he is more likely to produce across the board numbers than either Hosmer or Jennings. Jennings is a safer bet to deliver SBs and runs, but it will be a crap shoot with his BA and HR. I think you gain more with Lawrie than you give up by passing on the SBs (you can get the extra SBs elsewhere on your roster). I also think 3B is far more valuable than OF. I really like Hosmer, but I see 2013 as a stepping stone for him before putting it together in 2014 (what the H do I know? I have no crystal ball). I think Hosmer and Lawrie are very close, but 3B>1B; Toronto offense > Royals offense; and Rogers Centre > Kauffman Stadium.
I know it might be more like 2014 or 2015 before Moore really puts it all together, but Tampa knows how to handle their SPs, and Moore already has great k/9. If he even comes close to his upside, he will bring more value than Hosmer or Jennings.
Help with mine? 20/20 potential and I think he is more likely to produce across the board numbers than either Hosmer or Jennings
