This is what I mean, why compare the Cubs to the Stros, Sox, Indians, and Dodgers. What does it prove, beyond other teams with prospects that fail to walk often. The reason why you use top 10 prospects is b/c despite the small number, most who make an impact (starter) will come from the top 10 in each organization. The 10-30 range will likely consist of bench players or never make it to the majors. again, allow me to preface this by stating that I wish the Cubs organization emphasized plate discipline and patience more. I understand what you are saying about the top ten turning into starters, but your methodology is still extremely problematic. for instance, if Murton had about 10 fewer plate appearances, he would be on BA's Cubs top 10 (although that would bump Patterson off the list). also, when projecting future starters, using BA's list is extremely problematic because they so heavily emphasize ceiling. thus, Ryan Harvey makes their list, but he is far from certain to be a starter. as alluded to above, BA excludes guys that take a long time to figure it out, so Sing is excluded. BA also is unkind to players who lost the sparkle they had a couple years ago, so players like Scott Moore don't make it (as another example of this, Dope has another bad year, and he's no longer in this equation). finally, using this methodology skews the numbers when a player or two, ie Harvey and Dope, don't take a walk. in sum, using BA, or plucking any random set of 4 or 5 prospects to prove a point about the overall organization is not an precise enough method. if there is a prospect list out there that ranks in terms of "10 position players who will help within the next two years, starter, platoon or bench, maximum 175 major league plate appearance" the list very well may be Murton 33/347 Cedeno 20/245 Pagan 49/516 Pie 16/240 Sing 91/409 Theriot 45/448 Greenberg 56/305 Fontenot 59/379 Soto 48/292 Moore 55/466 using those players, instead of focusing on guys that might be complete busts even though they are potential starters or stars, and the Cubs minor league prospects average about 65BBs per 500 ABs.
