So it looks like Randy Youngman has some interesting insight to provide about Teemu and Kariya.

If you take a look at the comments section in his article about rebuilding the defense, you'll notice two comments - one about Teemu and one about Kariya.  Based on information that Youngman apparently knows, he's stated the following:

On Teemu

Teemu won't come back to a team that's Rebuilding, he said so in so many words earlier. I'd be surprised if he returned, although I'd like to see him play one more!

I'll be surprised if he doesn't come back, based on everything he told me.

On Kariya

Thanks Randy. I'd expect Rusty to return because Vancouver may need to retain Bieksa going into this season due to an injured blueline. Paul Kariya will be back in my opinion so our favorite Duck Teemu can play on the same line with his two good friends for the next two years. Bobby Ryan to give up number 9? This adds fuel to Bobby being traded. Your thoughts?

I'd be surprised if Kariya came back to the Ducks. Last I heard, he was closer to retiring than playing next season.

I'm a bit surprised that Kariya would actually be leaning towards retirement. He definitely can contribute to any team he's on.  I really do think he's still good for 25 goals, which let's be honest, every team could use.

I wonder how much of this we should actually believe.  At least it's from a reporter, right?
