Heck, I'll throw a version in, if only to give people a chance to all me an idiot!
I should state that I have always been in favor of balance, not a lopsided acquisition like Eichel. I think that Sakic blew it on this count, likely because of too much confidence ( misplaced) in Jost and JTC.

I think that looking at any line-up without looking at defense leads to inaccurate decisions about this team. Makar is an offensive monster. Girard and Toews have good offensive skills. Byram might turn out to be Makar Jr this season. It is not as if there are 3 Murray and 3 Graves back there. And wiht a partner like Murray - as opposed to Gravy - Makar would know that somebody is covering the blue line, letting him freelance a bit.
Let's start with Line 2. Bura and Mikko are potent wings, but that puts the two best snipers on one line. Why ruin that by centering it with Kadri? He is too selfish to drive plays t the snipers. Landy takes most of Mac's face-offs as it is. He is disciplined. So putting him on a line with the two snipers, plus Girard / Toews as the second pair, makes that a formidable scoring line.
Line 1: I realize placing Kadri there sounds crazy. But, again, Makar is essentially another wing on that line. Kadri does not have to worry about driving the line. It also puts the best face-off man on the first line.
Line 3 has already proven some chemistry in limited minutes. That is a high intensity shut down line. I might even pair them against the opponents' #1 line, then allow Mac to feast on lesser lines ( and transitively, the sniper line facing other teams' third lines.)
I am not sure what to do with the 4th line. All three have speed. Maybe all three could be part of a trade for something better? Short of that, perhaps Bednar uses them intermittently to tire out the first line of opponents.
