Bradford pear tree that is overwatered with rain? Is it dead?

Question:I live in Texas, and it has rained about 100 feet of water this month. My Bradford pear tree lost all of its leaves after they turned brown. If you touch the tree, it is really squishy...waterlogged. All of the nurseries are saying to give up because they want to sell me a new tree. They are saying "cottony root rot". Well, when you scratch the branches..under the bark is still green. Is there a chance to live or should I hack away?

Answers:
I'm sorry but she's a goner. And don't replace it with another Bradford. Those are terrible trees and begin to self destruct when they reach about 12-15 years of age. I'm serious! Large branches begin to fall off - it has to do with the genetic engineering of the original trees. I had 10 of these trees in a house I moved into and I watched this process first hand.
