I'm in the "I wouldn't laugh too much camp" too. He's got a track record of being useful for about a year while he is motivated. I'm going to guess that he's motivated.
I'm also guessing that the CBJ are probably more of a motivator/villain to him these days than Babcock is.
It wouldn't shock me if he logs a respectable season for the Wings.
I think (hope) he realizes that he needs to play well next year with the Wings to continue his NHL career. I don't mind the signing, but only because the Wings need a more physical defenseman (Salei was a let down physically). The more upsetting thing for Wings fans is the fact that we've signed two defensemen and neither is top-4 right now.
