He's been on a line with Gage Quinney and Tyson Baillie for a while. The Rockets have also recently been going with a Morrissey-Bowey Chartier-Draisaitl-Merkley PP1, which is kind of silly but a lot of fun to watch.
I knew little of Quinney before his arrival, he was an afterthought in the Josh Morrissey trade but he has played quite well for us. Almost PPG in his last ~40 games.
Baillie is a jack of all trades guy, PPG-ish for the last 3 seasons. Was (somewhat) surprisingly passed over in the draft which I suspect was due to his skating. If he can continue to mesh with Draisaitl and the Rockets have a good run, I see him getting signed - at the very least he'll get some rookie camp shots.
I agree with both of you. Lethargic backchecks have been a constant since he came to Kelowna. Unfortunately, not much will be done with that here. He's good/productive enough to get away with it and both Quinney and Baillie are responsible defensive players.
As for moving his feet - he tends to stop moving when there is a puck battle and/or when there is a shift in possession in the o-zone. Definitely needs to improve this.
I'd submit that he needs to improve just about every aspect of his skating, from fundamentals like stride/posture, to explosiveness via plyos/weight training, to agility/edgework. While just about every prospect could work on these areas, Draisaitl has other tools that many guys could never sniff. If he is able to incrementally improve in these areas over the next few seasons, he could be a gem.
