Spoiler: in short, yes, he would be a worthy fourth overall pick.
Aside from his injuries, Cayden Lindstrom's draft season was quite impressive. He bullied his way around the rough and tumble Western Hockey League, scoring 27 goals and 46 points in just 32 games played.
He also added 66 penalty minutes, which showcases the one part of his game I haven't touched on yet: Lindstrom is mean. I'm not saying he's going to go out looking for trouble ala Mathieu Olivier. But, he's not afraid to throw his body around, or participate in post-whistle activities himself.
He's got a little bit of that "Tkachuk" to his game; in that he has the skill to score a lot of points, but the size and snarl to throw a big hit, or just crawl under the skin of his opponents.
When you put it all together, I don't think it's out of the realm of possibilty that Lindstrom could be a 30-40 goal, 60-80 point player in the NHL at his peak. I'm not sure I would want to draft him as the centerpiece to my franchise - but if I had someone like Adam Fantilli around, this is exactly the kind of player I would want to see play behind him in the lineup.
Lindstrom's combination of size, speed, skill, competitiveness, and grit; will make him a matchup nightmare on a future second line. For these reasons, he may be the best pick the Blue Jackets could make at fourth overall.
