A couple points:
1) Hall and Eichel mostly haven't been linemates at even-strength. They started the year together but were separated early on and it has been Olofsson-Eichel-Reinhart and Hall-Staal-Cozens lately, with a different winger here or there.
2) Being an Oilers fan that watched Hall closely from 2010-2016, I completely dispute the notion of Hall being lazy. He was the team's best player by a pretty wide margin until McDavid was drafted, and on some pretty terrible teams he managed to Corsi at just shy of 50%, netting +3 in 5 on 5 goals (261GF-258GA), while producing at a rate of 70 points per 82 games with 2 top 10 scoring finishes in the entire league over those 6 years. To my eye, he was the one making everything happen on whatever line he played on for those years. It would be fair to call him a bit soft/lazy defensively, but his forechecking and effort put into puck retrieval in the offensive zone are his bread-and-butter as a player. He came up with a lot of high-effort plays to make things happen for the team offensively, and tilted the ice positively on a lot of nights. The results as far as win-loss don't match that because he was only out there for 18-20 out of the 60 minutes in the game. I won't speak to coachability, and there is some smoke around his locker-room presence that I can't dispute though. A lot of this reputational stuff though (I think) is some immaturity (not uncommon for young, rich and famous people) and not always handling his emotions/frustrations well in his early 20s, playing on such a bad team.
To me, it feels like you're parroting some common HF rhetoric on this player without having seen them play.
