While the article itself is decent, I'm left wondering if there might have been something else to write about. Since this isn't an obvious rehash of a column from last year, or before that, the answer must be no.
Some of them know a lot about baseball history. Most know less than the average fan. Just because you are good enough to make it to the big leagues does not mean you spent your childhood memorizing the batting averages of the 1977 Seattle Mariners.
I suppose that's because they're more interested at being good at playing the game instead of being the next Peter Gammons.
