But there's too much randomness in baseball -- winning 60% of your games (that's 97 games) will almost guarantee a division title, and winning 70% (113) is almost unheard of; compare to the NFL, where division winners routinely win 75% of their games, or the NBA, where a division champ that wins 70% of their games (57) is pretty typical, despite far more mechanisms in place to keep the talent levels even -- to guarantee success once you're actually in the playoffs. Especially in the best-of-5 first round.
I don't know if it's randomness so much as the effect of playing more games (which tends to make the vast majority of teams settle closer to .500)...baseball plays twice as many regular-season games as hockey or basketball (162 compared to 82), and ten times as many as in football (162 vs. 16).
Also, a smaller percentage of teams making it into the playoffs in baseball, compared to the other sports, which gives fewer opportunities to a "just good enough" team to go on a lucky tear and advance deep into the playoffs, knocking off the favorites in the process.
