Trying to establish a college metric

There are about 350 players in the Majors that played Division 1 College Baseball. As college baseball drafting has become more important in the past decade (thanks to things like Moneyball), it seems crucial to develop a metric to measure the difference between Division 1 and the Major Leagues. I used Baseball Cube for the statistics, and they did not have most college stats before 2000, which is fine (I could have found them elsewhere), because we can stick to basically a decade of college baseball. I also did not include players that had a small number of at-bats at either the Majors or College. I excluded Rickie Weeks because his crazy numbers (3.9 PPG, .94 ABPP) would have skewed the data, and if anyone puts up those kinds of stats in college, of course you draft them. Anyone else missed is due to human error.
