Should I Take On A 2 Year Old Male?

A friend has a 2 year old male that she is trying to find a good home for. He is not house or crate trained and is not used to a fenced in back yard. He is used to roaming freely and she feels like he needs boundaries. He is great with children and other dogs.

I have an eleven year old Border Collie who is wonderful and loving, not a mean bone in her body. I have two young children and a fenced in back yard. We are an active family but both of us work.

My question is... am I crazy for wanting to take this dog on? Do you think a 2 year old male will be quick to house/crate train. I haven't met him yet and would like to see if he minds at all before coming to live with us, but just want to hear from Aussie owners/lovers if this could work?
