Why can't people look at the big picture? Do you truly think Gaborik is DONE? He'll never score 30-40 goals again. He'll never hit 70-80 points again? If you think that, then it was a fine trade.
But if you take the trade in context, and view it that he was stifled in a system playing with Richards, Boyle, Pyatt, etc, that doesn't focus on offense, after having shoulder surgery, and only played 35 games... in a 48 game season... Then it doesn't look like a good trade.
I'd bet you every dollar in my bank account that Gaborik scores more goals in the upcoming seasons than Dorsett and Brassard combined.
And why? Like I said, I'd take Gaborik's career as a track record, over a 3rd and 4th liner every day of the week.
Context and big picture view helps.
