Like I said earlier when you first brought it up. I'm a little concerned about it too, but it's nothing to worry about it yet. Glad a bunch of us see that!
It's funny though, I was going over our top prospects yesterday and comparing them to my post-draft list, and I actually thought Hallander has improved his stock in my book this season (still my 6th ranked)

.
I knew he was a good play driver, but I didn't realize the level he was actually at. I think it's silly people are coming in here looking at his production and just dismissing him. I've watched him play 4 (maybe 3) games this season, his play driving is fantastic, his defensive awareness is ++, and he's one of those players that does all the little things right. Even if the production never comes I truly think he's got the ability to be a Pierre Engvall-type (strong defensive impact, but two-way) player in the NHL, but I'd say his upside is much (much) higher.
EDIT: Man I just looked at Engvall's last (and only) season in the SHL (D+3). Not only did he lead his VERY good team in CF%, he had a +8.8 rel.CF%. The guy was destined to be a play driver at the NHL level. Hallander's numbers are similar in and is over a year younger than that season.
