NHL free agency is fast approaching, so let’s take a look at whom will be of interest to the Detroit Red Wings. Subject: David Clarkson. Clarkson, 29, is coming off two seasons that saw him be very productive, and he shoots right. The Wings could use a right-handed shot in their fold, especially one who could play right wing on a top-two line. Clarkson, who is a prolific shooter, would also seem to a good candidate to help out on the right point on the power play, which was non-existent during the Chicago series. Clarkson has spent his career so far with the New Jersey Devils. He was never drafted, and largely has been considered a grinder-type. He has 97 goals and 73 assists in 426 games over seven seasons. His 770 penalty minutes, meanwhile, indicate a propensity for taking far too many penalties, and his minus-32 rating is also a concern. He has bounced around on lines, and hasn’t been a picture of consistency — much like Wings forward Damien Brunner this past season, Clarkson was a scoring machine the first half, with 10 goals the first 14 games and then five the rest of the way.
