I have your gold medal Zippy!
I couldn't agree more with this. Not only that, but the late 30's Sundin, who was coming off a half-year layoff, started turning it up in the playoffs that year as well (he quietly was a PPG player for us in the post-season).
As far as other best free agent signings go, I think Dan Hamhuis and Alex Mogilny are front-runners. Hamhuis was an integral part of 2011, and was a star for us for a number of years, while Alex Mogilny scored 50+ goals his first year here. It's not Mogilny's fault that idiotic decisions by management (i.e. letting Ronning walk, not giving Almo an adequate replacement #1 center) hindered his effectiveness.
I'm not sure where Raffi Torres and Manny Malhottra will rank, but they have to be up there somewhere.
Mogilny wasn't a free agent signing. We dealt future Selke winner Peca & a 1st round pick for him.
