Hossa was carried by Toews, Kane and Keith he was a complimentary piece at best. How many cups did he win before signing there? Exactly. Hossa should be 3rd in this poll and only because the options after 1/2 are pretty bad.
Would anyone pick Hossa over Chara to start a team? lmao no, not even close.
You obviously didn't watch the Hawks during that time span.
Chara, who, no offense, was just as much of a complimentary piece as Hossa, brought one Cup to the Bruins while Hossa brought three to the Hawks.
First line winger/ first pairing defenseman= complintary pieces from this logic.
The question was the best free agent signing of the cap era and again, no offense, being a huge reason why a team won three Cups is more significant then giving team mates high fives in the dressing room.
As for Chara magically changing some invisible "culture" in Boston, they won one Cup. You can make a stronger case Hossa changed locker room culture considering they won three Cups.
They didn't start winning Cups until Hossa got there, sayin......
BTW, how many Cups did Chara win before he got to Boston?
