Take stealing bases...
Point
Statistically, a stolen base doesn't significantly raise the chances that you'll score more runs than you would have had you not stolen a base...unless you're successful on about 80% of your attempts. Why would you take that chance when the odds are stacked so precipitously against you?
Counterpoint
Stealing bases is one of the great things about baseball. You have the opportunity to roll the dice to see if you can give your team an advantage. Sure, there's a gamble, but that's exactly the human element that is extracted from the game by "stat heads".
Play nice...
