I was looking through a variety of prospect ranking sites and I noticed that the position of these three guys tends to constantly bounce around.  What are your thoughts on them?  Who will make the biggest impact once they reach the majors?  Who will have the best overall career?  Are there position switches in any of their future?  DIscuss.

Mike Moustakas - The Number two overall pick in the 2007 minor league draft by the Royals, Moustakas has shown enormous power potential, but has failed to capitalize on it in two seasons in the minors.  2008's lackluster showing was more excusable because of a huge 2nd half and a tough hitting environment, but didn't break through as expected in 2009 in High-A.  His position is also in question, as he could become an outfielder depending on what the organization does with Gordon.  John rated him a B+, and he is still young (21) and has potential to be a middle-of-the-order slugger.

Josh Bell - The most talented Orioles offensive prospect not named Matt Wieters, Bell rose the prospect ranks after a strong 2009 season in which he hit .295 with 20 HR between high-A and Double-A, coupled with a solid walk rate.  Is already 23 but has a relatively open door to the majors for 2011 after Tejada leaves.  John rated him a B saying he saw him as a solid regular but not a star, although other publications (namely Project Prospect) view him as the strongest of the 3B crop.

Lonnie Chisenhall - Formerly a shortstop, Chisenhall rose up the prospect ranks after a strong showing in High-A Kinston, hitting .276 with 18 HR in 388 ABs, but struggled in a smallish sample size in Double-A Akron, hitting .183 in 93 ABs, has a pedestrian K/BB, but is also only only 21 and should get an opportunity in 2011 at the latest, especially if Peralta falters.  John gave him a B+ rating, and some other sites have rated him the best of the 3B crop, but there are certainly questions even though he's likely better than that other Indians 3b prospect from a couple years ago who mashed in Kinston and then deflated after his promotion (anyone remember his name? I can't and it's driving me crazy)
