Yep. For 2013 batting title qualifiers, the top 50 (highest) K/AB-rate hitters have an aggregate OPS of .786. The bottom 50 (lowest) K/AB-rate hitters have an aggregate OPS of .748.
A 40 point OPS gap between teams is worth @75 to 100 Runs per year to the advantage of the higher OPS offense.
I know which group I'd rather take to battle.
