Adam Boqvist has missed many games this year, only tallying 5 points in 14 games played, but his main talents lie in his ability to keep the puck out of the net. Boqvist has the second best +/- on the team at +3, and that is very impressive on a team with a combined -29 goal differential.
Boqvist makes $2.6M for the next two years, and the oilers only have $386k in cap space. This means they would have to send a player back to Columbus, and possibly have them retain part of Boqvist's salary, so there will definitely be a pick involved as well if they do choose to acquire him.
