Really, I remember hearing this during a baseball broadcast where a commentor said how perfect 90 feet between the bases are. I mean, first off how did they come up with that number? It's long enough that the best hitters in baseball fail 2/3 times, yet short enough that a fast runner can beat out a weakly hit ball. Fast runners can steal a lot of bases, but even the best get caught. That's one thing in the game that definitely doesn't need to change.
