Time to bump this thread that has went over a year without a post.
Powell's having a good season. The numbers don't look great because the U18's are a low-scoring team this year, and don't play as much of an up and down style as last year, but he's been playing on the top pairing all year. Very reliable player. Doesn't do anything great, but is good in all-situations, and will probably turn into a good pro because of it. I also think he could probably be a PP2 and PK2 type of player at the NHL level, possibly even PP1.
I've seen him listed in the second round in some places. McKenzie has him #59, which is usually a good indication of how scouts view players. I'd have him a little higher in the second round. I have him listed as an early second-rounder, but second round seems to be a good range.
His numbers don't jump off the page and neither does his skill-set, but if you watch enough games of Powell, you appreciate his style of play.
