Oh yes they did.
All I could say was "what?"
I didn't even see they'd re-signed Brad Stuart and picked up Ty Conklin earlier, although those are significant moves as well. (Don't think Pittsburgh won't miss Conklin, maybe not as much as Hossa, but it'll hurt. Ask the Wings how important a backup goalie is.) But this, well ... obviously no one wins the Cup in July, but what Detroit's done in two days so far sure hasn't hurt their chances.
