How do you think Rutherford did this offseason? I say looking at everything, I say an A-. Let's look at all the signings and departures we have made:
First, we let Gerber, Cullen and Ward go for free agency, dumped dead weight in trades (Vasicek + Tverdovsky) and let our two rentals (Weight + Recchi) go back to their former teams. I say we dumped the right players considering all the replacements JR got.
At forward, We replaced Cullen, Weight, and Recchi with Letowski, Belanger and Walker. Walker (a complete steal for Vasicek

) has replaced Cullen very effectively with his consistent play. Belanger has filled Weight's role very nicely, as well for much less salary ($1.3 million compared to $3.5 million). We haven't seen much of Letowski, but after his concussion he has played well, and has given a spark on our third line.
On defense, we basically traded Ward and Tverdovsky for Gleason and Tanabe. Gleason has had some good games and bad games, but overall I really like his defensive play, and is the future of our defense along with Babchuk. Tanabe (aka. Snuggles

) is really soft, and is afraid to take a hit, but really, he is only #9 on our depth chart with all our D-men healthy.
At goal, Cam Ward really took over in the playoffs, and despite Gerber's excellent regular season play that season, we had to give Cam the starting job this season. We signed Grahame to be his backup. He was shaky in his first 2 starts, but has been great for us afterwards.
After all that analysis, you can say Rutherford did a pretty decent job this offseason after winning the Cup and increasing salaries for our core. Once the defense gets together and a few deadline acquisitions, we have a chance to defend the Cup.
