"No, not really. I understand what probability distribution is" Apparently you don't, or you would have made the following statement. "but I don't buy the fact that Casey Blake sucking year after year after year after year after year in those situations is due to the fact that it had to eventually happen to somebody and he's just the unlucky one. Poor Casey Blake, he can't be blamed for him being a choke artist, he's just unlucky! Every year!" Except for that year where he absolutely rocked with RISP and 2 outs, as someone pointed out. This is just the intellectual cousin of believing that a roulette wheel is due for black. It's a simple misunderstanding of how statistics works. "I really don't understand why people can't accept the fact that the mental aspect of the game sometime results in players reacting differently in important situations. Why is that so hard to believe? They aren"t robots, they're humans. Some people can handle the pressure, some people press and try to do too much. That's not probability distribution." Because there was no pressure in all those high school, college, and minor league games that they thrived in all the way up? "If I don't hit .300 in AA, I have to go back home and work in a factory for the rest of my life. But if I do, I'm a millionaire." That's no problem for these guys, but seeing a baserunner on second base makes them choke up?
