I think the last sentence of your statement there is a bit harsh.
I think part of the reason why Gaborik has struggled has been his play on the LW, which is why I'd put together a line of Kreider - Richards - Gaborik (RW) as my 2nd line. I'll agree that Torts' biggest error this year has been his shuffling of the lines.
Still, do you really think Gaborik is putting in 100%, or even 75%, effort night in and night out? He's not using his speed, he's not playing with any life (or JAM), he's lifeless and floating throughout the entire game. Playing on the other side of the ice is no excuse for that.
The reason why I'm hard on Gabby is because I know he's so much BETTER than what he's been this year. He's a superstar when he's on his game. He has the ability, he's gotta find it in himself to get out of his slump.
