Except, McDavid and Draisaitl are the best pair in the world and utterly dominate everytime they're on the ice. Add to that they play atleast 1/3rd of the game, means that for an entire period these 2 are on the ice.
The issue, as I see it, is making sure the 2nd line is dangerous and lines 3 & 4 play even, after that you're laughing.
You don't remove a situation of extreme advantage, because you might make mild improvements else where.
That Square peg is going to fit, I just need to hit a little harder.
