No, but it would mean they were the best team at this time of year.
Like all other sports, the hottest team in the tournament usually wins it.
If you truly want the best teams to play in the World Series, then eliminate all league playoffs and just let the two clubs with the best overall records for six months fight it out in October...
... kinda like it was when only the pennant winners went to the Series for the first 60-something years in Major League history.
Btw, not all posters are disciples of the crapshoot theory. I'll take my chances with the best group of star players in a short series.
Baseball is the sum deeds of isolated individuals. Batters all by themselves, facing pitchers all by themselves, with fielders trying to catch a ball before it hits the ground, and baserunners trying to score without teammates setting picks or blocking for them... stuff like that.
