Smooshy pickles

Opened a can of pickles today. They tasted like pickles, but were quite smooshy. Why?
From http://www.mrswages.com/faq.asp#10:

What causes soft or shriveled pickles?
A number of things, including:

* Holding cucumbers too long after harvesting. They must be processed within one day of picking.
* Growing conditions ... either too wet or too dry.
* Overprocessing. Begin your pickling immediately ... don't leave cucumbers sitting in water.
* Cucumber varieties not suitable for pickling. Those varieties include burpless and slicing cucumbers.
* Using cucumbers from poorly nourished or diseased plants.

Perhaps a combo of 1, 2, and 5 lead to the demise of my pickles.
