Hossa and Kopecky were likely a package deal. Kopecky was mainly responsible for getting Hossa to Detroit last summer, so Hossa is probably returning the favor. That's the only thing I can think of that explains paying Kopecky $1.2M per year, which is a definite overpayment.
I agree that it sounds like a bit of a package deal, but I feel better about the $1.2M when I see that Brashear is making $1.4M per year from the Rangers. I know they're not exactly the same guy, but it makes me feel better. And Walker will cost Tampa $1.8M -- I could talk myself into anything with that number.
