How Good of an Offensive Metric is OPSBI?Posted: June 16, 2011
Update: Just so everyone is clear: I do not agree with the concept of adding RBIs to OPS. If you are looking for a “quick stat,” I recommend looking at OPS all by itself; it does a fine job. The purpose of this was to simply look at OPSBI and see how well it correlates with a more advanced statistic.
Last night, Jim Bowden put up a post on ESPN.com, wherein he created a new stat called OPSBI. Basically, you take the OPS of a player, multiply it by 1000 and add RBI to it. I can honestly say I’ve never thought of doing this, but let’s see how it stacks up to an advanced hitting metric like Fangraphs batting runs. I took only players with greater than 1500 plate appearances in the past three years. This provides a 133 player sample. Here ya go:

R^2 of 0.84 with batting runs? Not as terrible as you may think.
