I think some of you guys are underrating the chemistry between Drai and Yamamoto.
Every time Yams enters the zone he stops back and looks for a late man. Drai does the same thing, just with a huge frame and insane puck protection. They love their drop passes and give-and-goes, I'd keep them together for the time being.
That said, I'd consider moving Puljujarvi up to McDavid's line, but it's probably best to let him establish some chemistry with Turris first. He was shuffled around way too much in his first stint here, I think we have to give him a bit of consistency. Really like what I'm seeing from him so far.
