Great stuff, Skydog. One thing I'm liking is that the Top Prospects seems to give a high weighting to stats over ratings - that will come in particular use to people who want to play with stats only.
EDIT: Spoke too soon. If you are playing with stats only, how would you know that a 25 year old in AAA who is 3-7 with a 7.23 in 74.2 innings would be the 5th best pitching prospect in the league! He is obviously up there for his 97 in stuff. Talk about a way to give away his true talent level!
EDIT2: This chap started 30 games but only pitched 62 innings?
