I'm going to provide a contrary opinion. I think the scoring rule makes sense. When a run is meaningless and a team makes no attempt to defend a steal, I don't see why the player should be rewarded with a steal. In such a situation, the runner did not "steal a base", but was "given a base for free".
Well, wouldn't that apply to hits and runs a bit, too? I mean if a team is up by 15, the pitcher isn't really going to care if he gives up a hit or two. Same with if they're down by a bunch.
What if that steal gets a guy in position and then he scores, and that sparks a rally and a huge inning? Suddenly that "meaningless" stolen base is the initiator for a huge comeback victory.
What about if a runner scores on a wild pitch in a game where it doesn't matter? You think the catcher's going to chase the ball with the same intensity he would in a tight game? No. Is that run going to be discounted as fielder's indifference? Nope.
There are too many what-if's and personal opinion calls involved with it to be a sensible rule, and it's not consistent with any other stats in the same situation. If the rule on SB's is that they don't count when they don't matter, then that should apply to every other stat, too, and that simply doesn't make any sense.
Just because that single play doesn't determine the outcome of a game doesn't mean that it didn't happen.
Edit: And also, I like the jokes, haha, baseball should start using them!
