I liked Jackson in his draft year, but his development has stagnated a little since. He plays a good contain defensive game and is tough to beat 1 on 1, and has a reasonable physical side to his game. He can move the puck adequately, but he won't ever be an impact player offensively. His skating is okay, but it hasn't really improved much since his draft year. Before his 18 yo year, I thought he was going to be a candidate to make the WJ team both of the last two seasons, but he hasn't stepped up to become an elite CHL defenseman like I thought he would. Maybe the new challenge of pro hockey will bring out the best in him and he will get back on track. I used to think he was a safe bet to be an NHL defenseman with an upside of a top 4 defensive defenseman, but I am now thinking that a bottom pairing regular who kills penalties and can eat up a few minutes is a more realistic upside.
I haven't seen Stoner since he was in the WHL, but my impression of him when he graduated from junior was as a guy who might have trouble with higher level competition. I am not prepared to speak extensively about him though, since I am not really informed on his progress this year at all. I worried when he was in the WHL that his assertive style of play required that he be one of the best players in his class, and when he reached pro hockey where he would be only average at best, he would struggle to adjust. Not sure though.
