The Cardinals had 3 hitters (Yadier Molina, David Eckstein, and Scott Rolen) manage to hit anything higher than .234 in the World Series last year.
The Cardinals had 2 hitters (Molina and Puljos) hit anything better than .240 in the LCS last year.
They did pretty good in the division series, though.
In the meantime, they had pitchers like Jeff freakin Weaver throwing shut outs.
They won because of their pitching.
If that makes you think your point has been made, then sure, but they won because of their pitching and because they got hot at the right time, despite being the worst team coming into the playoffs.
