How did Doug Weight become a Duck?

Traded for Andy McDonald, Michal Birner and a &th round draft pick in 2008. Rumor has it that Doug Weight isn't too happy about it but his time in St. Louis was coming to a end at the end of the year and if they kept him, his playing time and role on the team would be in Question. A great trade for St. LOuis at this point and one that will pay off by helping the blues contend for the playoffs this year. Also Doug will settle into a position player in Anaheim and will also be a great help to them.
