Judging from his interviews in and round the combine, he certainly doesn't radiant personality or charisma. But keep in mind, the dude is from Northern Alberta, and is perhaps lacking in the cultural capital of some of his peers that grew up in major cities, who just seem more confident and cooler. Or maybe he is just a quiet kid? Regardless, I am not sure how much stock teams will put into this.
The athletic testing is an interesting piece that can go both ways in the eyes of NHL teams. Does he have athletic limitations or has he not prioritized gym work at this stage? If he is able to dominate at the CHL level with a high body fat count and hardly ever stepping foot in a gym, maybe teams will think this represents a development opportunity? I don't have the answers here.
When I watch him, he looks like a very strong and powerful individual. He had no problems physically handling Lindstrom who is tall, athletic and heavy in their encounters this season.
