I think he'll eventually become a very solid 4/5. Whether that's here, with our current depth, remains to be seen. He's tough, is a great physical player despite his size, very strong, skates very well, isn't much of an offensive threat but excels passing the puck out of the zone. His defensive acumen is excellent, and I think that in time, just like fellow Minnesotan Mike Sauer, he can learn to join the rush and contribute ~20 points.
I thought that on many nights Lindgren was the best defender in Hartford, and I remember quotes from either Clark or McCambridge stating as much. He was recalled because he was the best defender down there. He's forgotten because he's not flashy, but he's still a really solid prospect.
It will piss me off in the prospect polls when he drops to #20 or something.
