Ooooh. Thanks for the caution notes!
What is his style? I never seen him play, puck mover? Hard nosed? Skater?
Christiansen is a good skater and a puck mover. Great shot, good vision, good passing.
When he was signed out of junior he had a great shot but that was about it. He's only 6'0 and was a bit on the weak side and not good defensively. But he's filled out well now and so far not bad defensively. He can still get outmuscled at times but not too often. He's very willing to throw a bodycheck.
Christiansen is a bit older than KJ and Bedard but I believe he's spent each summer for a long time (since they were kids?) playing with them in the BC group, and I think I can see it in some of his skilled play.
We're not rushing to label him a permanent top 4 guy yet. We all saw Jake Bean look like a top 4 D at times and then regress. Those two share some similar traits, although Christiansen is much stronger and doesn't get run over on the cycle, which was the big downside with Bean. I don't see much downside with having Christiansen out there.
