What do you purpose he does? Take Tatar off the third line, and then watch the other coach just match their top lines against the 3rd and 4th lines against the Wings?
I tell you what Q did. He matched he top lines against Datsyuk's line, and Zetterberg's line, obviously. But he made a point to go after the Wings 2nd line, and their 4th line. Why was the 3rd line mostly untouched? They generated the most today.
You move Tatar to Datsyuk's wing, especially when they are injured, you pretty much are in the same situation. Probably worse off. You still have a weak second line that MAY be able to produce just a little bit more; it's not proven. But you weaken the 3rd line so much that, THAT line will be a target. So will the 4th line AND the 2nd line. The other coaches will have a field day!
At least the 3rd and 1st line are clicking. THe 4th line...that is what it is. They do what they do. The 2nd line? At least Datsyuk can hold it together. the 3rd line? Tatar and Andersson are what hold that line together.
Get healthy...go from there.
