I just want to riff on this for a sentence or two.
A professional baseball pitcher is paid to destroy his arm. In other words, the act of throwing a pitch actively injures the pitcher’s muscle, bone and connective tissues (ligaments and tendons). No other act in sports does this that I know of. Even in an incredibly rough sport like the NFL it’s not the act of the player that leads to injuries normally but the acts of other players.
On scheduling and the length of season the simple fact is that determining which team is better than another in not entirely possible over 162 games. Most people don’t acknowledge this but the season is not long enough to guarantee that random factors do not overwhelm talent in determining winners and losers.
This is a part of the fact that baseball is, by far, the major American sport with the most inherent balance. Look at the top winning percentages from recent years for the major sports:
Hockey
2008 .654
2007 .722
Basketball
2008 .805
2007 .805
Football
2008 .813
2007 1.000 (!!!)
Baseball
2008 .617
2007 .595
In fact, the highest MLB winning percentage, the 1906 Chicago Cubs, came in at .721. So the highest EVER winning percentage was topped by six of the seven top teams in the other three sports.
If anything, more games would be required if the overall concern was to use the regular season to determine the ‘best’ teams make it to the post-season. But that would get out of hand pretty quickly.
For that matter, I did a study for SABR several years ago (it didn’t make print, dang it) in which I determined that even if the regular season did bring the top eight teams to the post-season the eventual World Series winner was essentially random. In my study I attempted to chose the ‘best’ team by contrasting winning percentage, team OPS, team ERA, and several other factors and found that only in the extreme where on playoff team was clearly dominant in all or almost all of the factors I used was there any tendency towards a winner. Otherwise which team took home the trophy was spread almost at random with teams that were worse in many factors, sometimes in all of them, winning. It was startling.
On the schedule, I personally liked the elegance of the National League schedule prior to the recent wave of expansions. Twelve teams in two divisions means that a team plays the other five teams in-division 18 times (9 home and 9 away) and the six teams in the other division 12 times (6 home and 6 away). As I said, elegant. But expansion and interleague have given that an axe to the neck. Now we need to just work it as best we can.
A balanced scheduled on both leagues? Agh. Playing each of the other 29 teams six times each (one series home and one away) would lead to a 174 game schedule. Elegant again, I admit, but you might as well just flip a coin and save people the time and effort. There’s simply too many teams and too few days off to make that work.
Or, to quote a great man…
