Here's my issue with these stats. An "out on base", is an "out on base" whether it's an aggressive baserunner getting thrown out at home by 2 feet, or it's pure stupidity, such as Herrera leaning off of first, or two runners ending up on the same base. There's something to be said for being ultra-aggressive, and I do agree with that, but it does seem that a lot of our base running "outs on base" are of the "oh my freaking God, I can't believe he just did that" variety. Like you, I don't watch enough games from other teams to know what is a normal percentage of "being stupid" or "being aggressive" outs on base. If I had to guess, my eye test tells me the Brewers would have a higher percentage of "being stupid" outs on base. I'm sure you're going to tell me there's no difference, but I respectfully disagree. I like that sites like fangraphs and B-R are attempting to quantify more and more parts of the game, but baserunning is not the same as batting, which is easily quantifiable.
