Unless the matchups change, and I doubt they will, the Kid line is really the 4th line. They get far and away the easiest minutes on the entire team both in terms of quality of opposition and offensive zone faceoffs. They kill those minutes, though, so that's still an advantage for the Wings.
They also have 3 really good wingers in the top 6 in Alfie, Franzen and Nyquist and middle forwards in Helm, Abdelkader and Miller that can hold their own defensively. They could be ok based on all that, but missing your top 3 centers is usually nearly impossible to overcome especially when your defenseman don't move the puck that well on the back end. It'll be a good test for Anderrsson, though.
