BsR and BsR
?I didn't realize the Fangraphs has chosen to use BsR to represent baserunning, meaning runs from non-batter events (like SB, CS) which they use wSB as notation, and runs from batter events (like taking extra base), which they use UBR as notation.
The wSB notation is in reference to the "w" in the "weighted" metrics inspired by wOBA. The "U" in UBR is inspired by MGL's UZR, who provides, I think, the UBR numbers. It's a nice notation for the w and U metrics.
But then, they combine the two into BsR. But longtime saberists know that BsR is the notation that Dave uses for his BaseRuns (as described by Patriot).
I don't know how Dave feels about it, but it gives me a chance to bring up BaseRuns, easily one of the least appreciated and most important metrics around. If giving it a new notation, or finding some different notation for Fangraphs' version of BaseRunning is the result, all the better.
You guys are creative. What have you got for me?
