The Sharks paid a steep price to acquire the 26-year-old Burns, who is eligible to become an unrestricted free agent after next season.
"There's such a shortage of high-end defencemen in this league," general manager Doug Wilson said. "That's why you better move quickly because other people are lined up and involved. There's just not enough good defencemen and centermen around in this league. When they do become available, if you hesitate you don't get them."
They sent a former 30-goal scorer who hasn't even reached his prime in the 24-year-old Setoguchi, last year's first-round pick Charlie Coyle and the 28th overall pick in this year's draft for Burns and a 2012 second-round selection.
They overpaid big time. They gave up a 30 goal scorer on an amazing contract, a very talented prospect who's going to be a very player in Coyle and a 1st round pick. I like Burns but there's no way he's worth that much. Great deal for Minny though, they get a goal scorer to play with Koviu and some more young talent.
