You are missing the point I think?
DeBrusk and Heinen both played in PRO in 16-17. DeBrusk had 19g/30a in 74 games and Heinen 14g/30a in 64 games. In the playoffs JDB had 6g/3a in 17 games while Heinen led the team with 9g/9a in the same number of games.
That training camp DeBrusk was stapled to Krejci’s left wing and Bjork was put on Bergeron’s right. Neither did anything special to earn it. Their rookie seasons, Heinen put up slightly better numbers than DeBrusk (16/31 vs 16/27) while moving around in the Bottom 6 while DeBrusk stayed with Krejci.
Last season, Heinen had a down year offensively while being moved around (again). DeBrusk had 27 goals but less points than the previous season, all the while staying with Krejci no matter how poorly or well he played.
I wonder how many points Heinen would have had the past two seasons if he was allowed to play with Krejci the entire time and given 1st line PP minutes?
I don’t want this to come off as anti-DeBrusk because I like him quite a bit. The fact remains that despite similar production they have been handled in completely different ways.
DeBrusk has certainly been granted some more stability in his position and less comment on his play that his numbers might suggest. It's been hard to evaluate him fully though. Last year was only his second season and it was impacted by two bad head knocks, one of which caused a definite concussion, and I'm pretty sure the second one did too even though he played on.
He was just getting going and looking good early-mid last season then he got that first delayed concussion. When he came back it took him a while to find his feet again, but he was back to producing and looking pretty decent going into the playoffs. Then Kadri wiped him out and again he struggled from them onwards and really didn't seem quite right.
So for me at least my opinion on him is reserved for the moment - I'm really hoping he gets a good long run of health this season and we can get a much better picture of just where he's at and what he can do.
