I am not suggesting that the Sox should not steal bases. All I said is that stolen bases are overrated. If any runner can steal successfully enough to beat the break even point, then that runner should continue stealing bases.
Here's a question for you and anyone else. How many games or runs do you think the Sox have added because of all of their base stealing?
The answer is, they are +7.8 runs on base stealing, not even one game, and they are the most successful base stealing team in baseball this year. I'm guessing that most people thought it was considerably more than that. Are those +7.8 runs important? Sure. Base stealing is important and definitely has its place in the game. Saying that it's overrated is not saying that it's unimportant.
As a side note, Minn, KC, Texas, and Colorado are all in the (slight) negative for base stealing, which suggests the break even point this year is somewhere around 72%.
