Who would you take out in order to bring in Nyquist? Surely he's not good enough for that top6, at least not on paper, then what? I thought both Landeskog and Soderberg were great, their line was probably our best in the whole tournament, shame they didn't get more minutes. Then there's Silfverberg and Hagelin, 2 players that had equal or better years than Nyquist last year. Silfverberg brought some size to that 4th line that was considered a pretty small 4th line with Kruger and Hagelin. Hagelin basically brings the elements that you said, at least the speed without a doubt. He might not be as good a goalscorer as Nyquist, but he surely fits that 4th line role much better than Nyquist, without being a grinder that can't do anything else.
I don't mind Nyquist, but i honestly can't see where he would have fit in on Team Sweden. Saying that we "aren't Canada" and that we can't leave out talented players seems strange, because on paper, we had talented players on all of our 4 lines. Even though they were obviously not on the same level as Canada's, but it's not like Nyquist would've changed that. Our 3rd and 4th line wasn't just pure grinding lines, though they could fit that role nicely if necessary.
