Going back to the league on my first post:
This is the league, with their corresponding GB-FB ratios (pitching, hitting)
OKS 1.40, 1.26
SPR 1.52, 1.29
COL 1.27, 1.52
RIC 1.28, 1.37
WIN 1.66, 0.90
SIC 1.28, 1.47
HOU 1.29, 1.52
HOB 1.23, 1.50
BRO 1.32, 1.42
FRE 1.34, 1.20
PUL 1.31, 1.38
MAG 1.28, 1.41
The average GB-FB ratio for both pitching and hitting is 1.35. So if you’re above that in pitching, that’s good, and if you’re below that in hitting, that’s also good.
Now, if you order the league by combined rank for both pitching and hitting, this is what you get:
Winning Inc combined rank is 1st: Won the Central, Lost the Finals
Freedom Riders combined rank is tied for 2nd: Wildcard, Won the Championship
OKS Ice18men2 combined rank is tied for 2nd: Won the East
Springfield Atoms combined rank is tied for 2nd: League high run diff of +92 but missed playoffs
Bronze Bluebirds combined rank is 6th: Won the West
What does this mean to you?
Maybe not much, because it’s only one league.
What does this mean to me?
Ground balls help your pitchers prevent runs, and fly balls help your hitters accumulate runs. The GB-FB ratio correlates very well with slugging. Having said that, when you sacrifice balance for one very high dimension, you probably give up some overall effectiveness. Too much of a good thing, whether it be home runs, stolen bases, or anything else, likely will only get you so far.
I don’t think maximizing your GB-FB ratio acts as a magic bullet, however, there may be something toward having a certain amount of awareness regarding GB-FB (ie SLG) when you build your teams. You may believe an out is an out is an out or a hit is a hit is a hit, but those results are not necessarily created equally.
