In my 2013 review of Fantasy Baseball Rankings, I noted how the majority of a team’s success (in 12-team mixed roto leagues) can be tied to the end-of-season value of their team.  Those stats are:

• Drafted Hitter+Pitcher End of Season Value – 66.9% correlation with Team Total Standings Points (2013)
• Drafted Hitter End of Season Value = 70.5% correlation with Team Hitter Standings Points (2013)
• Drafted Pitcher End of Season Value = 60.0% correlation with Team Pitcher Standings Points (2013)

The below graph shows the cumulative round-by-round impact of how a team’s draft drives a fantasy team’s success (or lack thereof) in the 2013 Razzball Commenter Leagues (so the end of season value of a team’s 1st-4th round hitters explains about 53% of a team’s hitting standing points (red line), 1st-4th round pitchers explains about 9% of a team’s pitching standing points, and the sum of the two explain 40% of a team’s total standings points)
